function::long_to_fp - Linux

Overview

The function::long_to_fp command converts a 64-bit long integer to a floating-point number. It is typically used when working with precision calculations or when interfacing with other systems that require floating-point representations.

Syntax

function::long_to_fp [--help] [--version] [--man] <integer>

Options/Flags

• --help: Display a help message and exit.
• --version: Display the command’s version number and exit.
• --man: Display the command’s manual page and exit.

Examples

Basic usage:

function::long_to_fp 1234567890

Output:

1.23456789e+09

Using a negative integer:

function::long_to_fp -1234567890

Output:

-1.23456789e+09

Common Issues

• Invalid input: The input integer must be a 64-bit long. If an invalid integer is provided, the command will display an error message and exit.
• Overflow: If the input integer is too large or too small to be represented as a floating-point number, the command will display an error message and exit.

Integration

The function::long_to_fp command can be combined with other Linux commands to perform more complex tasks. For example, the following command converts a file size to a human-readable format:

du -sh / | function::long_to_fp | bc -l | sed 's/[^0-9.]//g'

Related Commands

• function::short_to_fp: Converts a 32-bit short integer to a floating-point number.
• function::integer_to_fp: Converts an arbitrary precision integer to a floating-point number.
