This question touches on a limitation of the Bash shell–namely, that it does not understand floating point arithmetic and treats such numbers as strings. The round-up approach leverages the shell behavior to round toward zero (0). However lets say diff is -0.17 and minm is -0.0017. _output=`echo “$num1 >= $num2” | bc` In such a case the comparison seems to fail.

Sometime, we need to compare floating values in bash. To make it work, we have to use "bc" command. For example “bc” utility but its not 100% reliable for all scenarios although it can be handly if you just want to check if the two numbers are equal or un-equal. A floating-point arithmetic In Bash shell, we can only perform integer arithmetic. Native bash: you can't Two options: 1. move your script to another language with real number support (e.g. ‘{ printf(“%03d%03d%03dn”, $1,$2,$3); }’ Among them, printf is quite fast. If we want to perform arithmetic involving a floating point or fractional values, then we will need to use various other utilities, such as awk , bc , and similar. Is the correct way to compare a mixture of positive and negative numbers in bash. In integer comparison, we used “lt/le/eq/gt/ge”, which makes possible to compare integer values in bash script. }, num1=`rpm -q bash | awk -F “-” ‘{print $2″.”$3}’` Please help. Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. # /tmp/compare.sh When comparing strings in Bash you can use the following operators: string1 = string2 and string1 == string2 - The equality operator returns true if the operands are equal. For example in the below script I have two values Bash float comparison - bc. Line 6 - The backslash ( \ ) in front of the single quote ( ' ) is needed as the single quote has a special meaning for bash and we don't want that special meaning. External commands like bc or awk or perl can be used to round numbers as needed. But like we can compare integers in bash, will not work for floating numbers. The function testEquality calls calculate(x,0.2f,45) for every value from 9.0 to 1009 in steps of 0.1 and produces actual =x -9 as the result. 2.15 is lesser than 2.3 Let's break it down: Line 4 - Let's see if the first command line argument is greater than 100; Line 6 and 7 - Will only get run if the test on line 4 returns true. else else let¶ A Bash and Korn shell built-in command for math is let. else Following are the topics, that we shall go through in this bash for loop tutorial.. If I execute the same How to compare float numbers. dc has a limited ability to operate on strings and on numbers; the only things you can do with strings are print them and execute them as macros (which indicates the contents of the string are processed as dc commands). + num2=2.3.6 # Split and join the version numbers with “.” instead of “-“    echo “$num1 is greater than or equal to $num2” Lets execute our script    echo “$num1 is equal to $num2” echo “$num1 is greater than or equal to $num2”, ++ awk -F .

Let us take the same example as above with different value I have tried several methods. GitHub Gist: instantly share code, notes, and snippets. To check if two strings are equal in bash scripting, use bash if statement and double equal to == operator.. To check if two strings are not equal in bash scripting, use bash if statement and not equal to!= operator.. Thanks in advance: Vikas Singh However, what if we use floating point in Bash shell? In other word operator dictates the type into which the variable is converted before performing a particular operation. The one reliable way I use is to convert the version numbers into integer values. + num2=3.2.147.30.1 Although if you want to do simple comparison i.e. + num1=2.15.4 num2=`echo $num2 | sed -e ‘s/-/./g’`, if [ “$(convert_to_integer $num1)” -ge “$(convert_to_integer $num2)” ];then python or perl). We will now create a script for doing numeric comparison, but before we do that we need to know the parameters that are used to compare numerical values . ; var++: Post increment operator, result of the variable is used first and then variable is incremented. It works well for most of the cases. The if statement allows you to specify courses of action to be taken in a shell script, depending on the success or failure of some command. In integer comparison, we used “lt/le/eq/gt/ge”, which makes possible to compare integer values in bash script. ‘{ printf(“%03d%03d%03d%03d%03dn”, $1,$2,$3,$4,$5); }’ Let’s see with examples what exactly happen in case we treat floating values and integer with same comparison operator. Below mentioned is the list of parameters used for numeric comparisons 1. num1 -eq num2check if 1st number is equal to 2nd number 2. num1 -ge num2checks if 1st number is greater than or equal to 2nd number 3. num1 -gt num2checks if 1st number is greater tha… You can have as many commands here as you like. But what if I made it more tricky like below Bash only evaluates expressions with non-floating point numbers. Provisioning AWS EC2 Instance with Ansible. GitHub Gist: instantly share code, notes, and snippets. The main gotcha here has to do with the fact that "*", "<", and ">" have other meanings in bash.    echo “$num1 is greater than or equal to $num2” In terms of performance, they aren’t really comparable. You can perform math operations on Bash shell variables.

Sorry, your blog cannot share posts by email. I have a bash script with the following line where timestep is a decimal number. Comparison of floating point numbers in bash I have the following code snippet in bash if ]; then minm=`echo "$diff" | bc` fi It works well for most of the cases. In Bash shell scripting we can perform comparison of the numbers. looks like this gives us the perfect comparison, Lets see what is happening in the backend num2=2.3.6 This is completely different approach from the most of programming language in which comparison operators are "polymorphic"-- work for all types of operators such as integers, floating point numbers and string. Among them, printf is quite fast. So there is no built-in function for rounding up or down floating point numbers. For doing strings comparisons, parameters used are. Tips To Stay Safe On The Internet And Prevent Hacking, How to configure and Install kdump (crashkernel) in RHEL/CentOS 7, Step by step guide to implement/modify quota (soft and hard limit) for user, add/modify grace period and more in Linux with examples, How to fix “NoValidHost: No valid host was found. Sometime, we need to compare floating values in bash. # sh -x /tmp/compare.sh ++ echo 2.3.6 This sets the scale in bc to the value of the bash global variable float_scale, which is by default set to two (near the top of the script). Bash documentation even goes on to say this: “When not to use shell scripts …    echo “$num1 is greater than or equal to $num2” However lets say diff is -0.17 and minm is -0.0017. Operator Syntax Description Example eq INTEGER1 -eq INTEGER2 INTEGER1 is equal to INTEGER2 #!/bin/bash read -p "Please enter and confirm number 10 via keyboard : " n 2.21 is not equal to 2.31 if two floating/version numbers are equal or un-equal then you have plenty of tools. It is a conditional statement that allows a test before performing another statement. Example – Strings Equal Scenario With this small bash script we can easily able to understand, why we shouldn’t compare floating numbers as we do integer.Let’s see one way I used to compare floating numbers. fi, If I execute the above script ↩ Boost libraries are usually high-quality and thoroughly reviewed, so please contact me if I’ve missed some critical observation. To printf floating point numbers a %f specifier is our friend: $ printf "%f\n" 255 0xff 0377 3.5 255.000000 255.000000 377.000000 3.500000 The default behaviour of %f printf specifier is to print floating point numbers with 6 decimal places. /tmp/compare.sh: line 7: [: ==: unary operator expected Post was not sent - check your email addresses! So there is no built-in function for rounding up or down floating point numbers. (standard_in) 1: syntax error 2.21 is lesser than 2.30 You can calculate a floating-point precision percentage in Bash using the printf method and Arithmetic Expansion, or you can calculate a rounded integer percentage using Arithmetic Expansion with the ((...)) notation. The short and direct answer is using ‘ bc ‘ command – “An arbitrary precision calculator language.” Just run bc and enter some floating point calculation expression, such as “1.2+8.2”, bc will give the result. 2. Why Choose Desktop and Why Choose Mobile Gaming? Bash is a true interpreted language, and the shell makes little attempt to do any sort of “compilation”. To perform bash compare numbers operation you need to use “test” condition within if else loop. Hi Frnds, I need to write a script that will compare a float number and interger and show which is greater. It works well for most of the cases.
