BinaryFormat.UnsignedInteger32

Binary

A binary format that reads a 32-bit unsigned integer.

Syntax

BinaryFormat.UnsignedInteger32(binary as binary) as any

Parameters

Name	Type	Required	Description
`binary`	`binary`	Yes	The binary data to read the 32-bit unsigned integer from.

Return Value

function — A binary format function that reads a 4-byte unsigned integer from binary data.

Remarks

BinaryFormat.UnsignedInteger32 is a binary format specifier that reads a 32-bit (4-byte) unsigned integer from binary data. The value range is 0 to 4,294,967,295 (UInt32 / uint).

The default byte order is little-endian (least significant byte first). Use BinaryFormat.ByteOrder to wrap this format if the source data uses big-endian byte ordering.

This format is widely used in binary file formats for sizes, offsets, counts, magic numbers, and other 32-bit unsigned values. Many file format headers (e.g., PNG, ZIP) use unsigned 32-bit integers extensively.

Examples

Example 1: Read a 32-bit unsigned integer

let
    binaryData = #binary({0x01, 0x00, 0x00, 0x00}),
    result = BinaryFormat.UnsignedInteger32(binaryData)
in
    result

Example 2: Read a larger 32-bit unsigned integer

let
    binaryData = #binary({0x00, 0x00, 0x01, 0x00}),
    result = BinaryFormat.UnsignedInteger32(binaryData)
in
    result
