Raise to the power in shell

How do you raise m to the power of n? I've searched for this everywhere. What I found was that writing m**n should work, but it doesn't. I'm using #!/bin/sh.


I would try the calculator bc. See http://www.basicallytech.com/blog/index.php?/archives/23-command-line-calculations-using-bc.html for more details and examples.

eg.

$ echo '6^6' | bc

Gives 6 to the power 6.

For some formulas, you can write your own functions to handle all aspects of an equation. What I have covered just showed some of the most basic approaches to working with math in PowerShell, but you should definitely expand out and see what other uses you can come up with.


Using $n**$m really works indeed. Maybe you don't use the correct syntax to evaluate a math expression. Here's how I get the result on Bash:

echo $(($n**$m))

or

echo $[$n**$m]

The square brackets here are not meant to be like the test evaluator in the if statement so you can you use them without spaces too. I personally prefer the former syntax with round brackets.

Shell Scripting: calculate power of a number with a real number as , You cannot directly use the ^ operator to raise to a non-integer exponent, however, you can use the identity. ab = eln(a) × b. with e being the  Example. The following example uses the ^ operator to raise a number to the power of an exponent. The result is the first operand raised to the power of the second. Dim exp1, exp2, exp3, exp4, exp5, exp6 As Double exp1 = 2 ^ 2 exp2 = 3 ^ 3 ^ 3 exp3 = (-5) ^ 3 exp4 = (-5) ^ 4 exp5 = 8 ^ (1.0 / 3.0) exp6 = 8 ^ (-1.0 / 3.0)


using bc is an elegant solution. If you want to do this in bash:

$ n=7
$ m=5

$ for ((i=1, pow=n; i<m; i++)); do ((pow *= n)); done
$ echo $pow
16807

$ echo "$n^$m" | bc  # just to verify the answer
16807

Script to raise a integer by a exponent (while loop), I am trying to write a script that raises a integer (m) by a exponent (n) using a while loop ex. 5 raised to the power of 2 . I want a shell script to monitor this path. PowerShell is an advanced form of command prompt. It is extended with a huge set of ready-to-use cmdlets and comes with the ability to use .NET framework/C# in various scenarios. Today, I will show you how to start a process elevated from the PowerShell prompt. Earlier, I covered how the same can be done from a batch file.


You might use dc. This

dc -e "2 3 ^ p"

yields

8

There  When using Powershell, you may need to run Powershell as an administrator to perform a specific task. The reason for this is the User Account Control (UAC). Introduced with Windows Vista User Account Control (UAC) keeps the user in a non-elevated state if not explicitly told to be elevated as an administrator.


My system admin didn't install dc so adding to other correct answers, I bet you have not thought of this -

a=2
b=3
python -c "print ($a**$b)"
>> 8

works in bash/shell.
