Example

// Extract the real found at byte 52 of Xyl.raw file

// Load the buffer corresponding to the Xyl.raw file
bMyBuffer is Buffer = fLoadBuffer("C:\Test\Xyl.raw")
// Check that it loaded properly
IF bMyBuffer = "" THEN
Error("Error while reading the buffer")
RETURN
END
// Extract the real found 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 the 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 is sought. 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 sought real is coded. 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).
