Editor to share with you the use of linux bc command floating-point operations, I believe that most people do not know much, so share this article for you to learn, I hope you will learn a lot after reading this article, let's go to learn the method!

Bc, which is spelled "Binary Calculator" in English, is a calculator language that supports interactive execution with arbitrary precision. Bash has built-in support for four operations of integers, but does not support floating-point operations, and the bc command can easily perform floating-point operations, and of course integer operations are no longer needed.

Syntax format: bc [options]

Common parameters:

-I force into interactive mode-l defines the standard math library used-w defines the standard math library used-Q prints normal GNU bc environment information

Reference example

Arithmetic operation advanced operation bc command it can perform floating-point operations and some advanced functions:

[root@linuxcool ~] # echo "1.212 # 3" | bc

3.636

Set the decimal precision (range of values):

[root@linuxcool ~] # echo "scale=2;3/8" | bc

. 37

Calculate the sum of square roots:

[root@linuxcool ~] # echo "10 ^ 10" | bc

10000000000

[root@linuxcool ~] # echo "sqrt (100)" | bc

10 above is all the contents of floating-point operations using linux's bc command, thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
