Byte Conversion Library for Crystal

This library provides methods for converting numbers (signed and unsigned integers, and floating point types) to and from byte arrays in Crystal programming language. The methods support both little-endian and big-endian byte orders.

Everything in this repository, including the code, tests, and README has been created by ChatGPT-4 with some guidance.

Features

• to_bytes, to_le_bytes, and to_be_bytes methods for converting numbers to byte arrays
• from_bytes, from_le_bytes, and from_be_bytes methods for creating numbers from byte arrays

Installation

Add this to your application's shard.yml:

dependencies:
  bytes_ext:
    github: mamantoha/bytes_ext

Usage

require "bytes_ext"

# Convert an Int32 to its byte representation
i32 = 0x12345678_i32
bytes = i32.to_le_bytes
# => Bytes[0x78, 0x56, 0x34, 0x12]

# Convert a byte array to an Int32
new_i32 = Int32.from_le_bytes(bytes)
# => 0x12345678_i32

# Convert an Int64 to its byte representation
i64 = 1234_i64
bytes = i64.to_le_bytes
# => Bytes[0xD2, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]

# Convert a byte array to an Int64
new_i64 = Int64.from_le_bytes(bytes)
# => 1234_i64

# Convert a Float32 to its byte representation
f32 = 12.5f32
bytes = f32.to_le_bytes
# => Bytes[0x00, 0x00, 0x48, 0x41]

# Convert a byte array to a Float32
new_f32 = Float32.from_le_bytes(bytes)
# => 12.5f32

# Convert a Float64 to its byte representation
f64 = 12.5
bytes = f64.to_le_bytes
# => Bytes[0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]

# Convert a byte array to a Float64
new_f64 = Float64.from_le_bytes(bytes)
# => 12.5
