Stored procedures
Extracts a real from a binary buffer at a given position.
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).
