BitRange Calculator

Simple command-line tool written in Rust that calculates and formats the maximum, signed, and unsigned ranges of integers based on a given bit size. It helps to understand the range of values that can be represented in binary for a specified number of bits.

Features

• Calculate the maximum value for an unsigned integer based on the number of bits.
• Calculate the signed integer range (both positive and negative) based on the number of bits.
• Format large numbers with commas for easy readability.
• Supports flexible bit sizes (positive integers only).

Usage

The program prompts you to enter the number of bits. Based on the input, it calculates the following:

• Maximum value for an unsigned integer.
• Formatted maximum value for an unsigned integer with commas for readability.
• Signed integer range showing the minimum and maximum values.
• Formatted signed range with commas for readability.

Examples: Note: These are outputs from the app.

16-Bit Calculation:

Max value for a 16-bit unsigned integer: 65535 (65,535)
Signed range for a 16-bit integer: -32768 to 32767 (-32,768 to 32,767)

32-Bit Calculation:

Max value for a 32-bit unsigned integer: 4294967295 (4,294,967,295)
Signed range for a 32-bit integer: -2147483648 to 2147483647 (-2,147,483,648 to 2,147,483,647)

64-Bit Calculation:

Max value for a 64-bit unsigned integer: 18446744073709551615 (18,446,744,073,709,551,615)
Signed range for a 64-bit integer: -9223372036854775808 to 9223372036854775807 (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807)
