Functions
unsigned int	toiFloat (const char *str, int width)
float	fromiFloat (unsigned int x, int width)

Detailed Description

This file defines the interface to a C file convert.c that converts between float and unsigned int types. Thus, you do not need to declare ANY float variables anywhere in your code. Note that the test driver testFloat.c does not use any float variables. While the declared variables are <ocde>int, and thus have 32 bits, the width parameter defines whether the lower 16 or all 32 bits hold the relevant information.

Function Documentation

float fromiFloat	(	unsigned int	x,
		int	width
	)

Convert a iFloat_t to a float

Parameters

x	the unsigned int containing bits for a IEEE floating point value
width	the "size" of the representation (32 or 16)

Returns

the value as a float

unsigned int toiFloat	(	const char *	str,
		int	width
	)

Convert a string to a iFloat_t

Parameters

str	the string to convert
width	the "size" of the representation (32 or 16)

Returns

an unsigned int containing the IEEE floating point value
