BufferToReal (Function)

In french: BufferVersRéel

Extracts a real from a binary buffer at a given position.

New in version 2025

This function is now available in browser code.

Example

// Extract real at byte 52 from the Xyl.raw file

// Load buffer that corresponds to the Xyl.raw file
bMyBuffer is Buffer = fLoadBuffer("C:\Test\Xyl.raw")
// Check loading
IF bMyBuffer = "" THEN
	Error("Error reading buffer")
	RETURN
END
// Extract real at byte 52
rMyReal is real = BufferToReal(bMyBuffer, 52)

Syntax

<Result> = BufferToReal(<Buffer to use> [, <Position> [, <Number of bytes to read>]])

<Result>: Real

Real extracted from buffer.

<Buffer to use>: Buffer

Name of the buffer variable loaded in memory that contains the real value to find. This parameter can also correspond to an ANSI or Unicode string.

<Position>: Optional integer

Position at which the real will be searched. The first position of the buffer corresponds to 0.
By default, <Position> is set to 0.

<Number of bytes to read>: Optional integer

Number of bytes on which the real is encoded. The value of this parameter is set to 4 or 8.
By default, <Number of bytes to read> is set to 4.

Remarks

By default, the real is read at the beginning of the buffer as a 4-byte real.
The bytes are read in Little-Endian mode (the low byte is read first).
