csqrtf - Linux

Overview

csqrtf calculates the complex square root of its input and produces the output in complex rectangular format. The command provides a versatile tool for performing complex number operations and analyzing complex data.

Syntax

csqrtf [-hqv] [--help] [--quiet] [--verbose] [complex number expression]

Parameters:

• complex number expression: Specifies the complex number for which to calculate the square root. Use the format <a> +/- <b>i, where <a> and <b> represent the real and imaginary parts, respectively.

Options/Flags

• -h, –help: Display help information and exit.
• -q, –quiet: Suppress all output except errors.
• -v, –verbose: Enable verbose output, displaying intermediate calculations.

Examples

Simple Calculation:

csqrtf 4 + 3i

Output:

2 + 1.5i

Complex Expression with Multiple Terms:

csqrtf (1 + 2i) * (3 - 4i)

Common Issues

• Invalid Input: Ensure that the input is a valid complex number expression.
• Imaginary Part of Root: The imaginary part of the square root may be negative.
• Large Input Values: Very large input values may result in overflow errors.

Integration

Chain with Other Commands:

echo "1 + 2i" | csqrtf | awk '{print $1}'
