What is dc MacOS command?

The dc command on MacOS is a versatile tool for performing complex mathematical calculations with arbitrary precision. It uses a reverse Polish notation approach, where operators follow the operands. This allows for efficient calculation of various mathematical expressions, making it a powerful utility for scripting and automation tasks.

dc Syntax:

dc [options] [operands]

dc Options:

Option	Description
-e expression	Specify a calculation expression to be executed
-f file	Read input from the specified file
-o	Output results in octal format
-i	Ignore invalid characters in input
-S	Operate in stack-only mode
-r	Output results in radians
-D	Output results in debug format
-T	Output results in trace format

Parameters:

Parameter	Description
expression	Calculation expression to be evaluated
file	File containing input operands
operands	Operands for the calculation

dc Command Usage Examples:

Perform Basic Arithmetic Operations

echo "3 5 + p" | dc

Calculates the sum of 3 and 5 using dc.

Calculate Factorial

echo "5 1-" | dc -e 'k[1-d0<b]dsbx'
