Syntax
- (read-float [stream [length]])
- stream - the input stream (default is standard input)
length - the length of the float in bytes [default is 4,
legal values are -4, -8, 4, and 8]
returns - the float
Description
The 'read-float' function reads a binary floating point
number from an input stream, created by the
open-binary function.
Note: Integers and floats are assumed to be
big-endian [high-order byte first] and signed,
regardless of the platform. To read little-endian
format, use a negative number for the length, e.g. '-4' indicates a
4-bytes, low-order byte first. The file should be
opened in binary mode.
