bc is an arbitrary precision calculator language that supports both integer and floating-point arithmetic. It can handle complex mathematical operations, including trigonometric functions, logarithms, and more. bc is often used in shell scripts for calculations that require high precision.
bc is programming language by it self, So you can define variables too. Enter bc interactive mode and define your variables in each line:
If basic calculation is not enough for you, a standard math library is also available by the command line option -l or --mathlib. If requested, the math library is defined before processing any files. By typing executing bc -l command, you can enter interactive mode with standard math library defined as well:
