3.35 Rounding (Unbiased) of a Floating Point Scalar
Description:
This module performs the unbiased rounding of a floating point scalar.
Header File:
FPU.h
Declaration:
float32 rnd_SP_RS(float32 x)
Usage:
y = rnd_SP_RS(x);
float32 x
input value
float32 y
result
Alignment Requirements:
None
Notes:
1. numerical examples:
rnd_SP_RS(+4.4) = +4.0
rnd_SP_RS(-4.4) = -4.0
rnd_SP_RS(+4.5) = +5.0
rnd_SP_RS(-4.5) = -5.0
rnd_SP_RS(+4.6) = +5.0
rnd_SP_RS(-4.6) = -5.0
Example:
#include "FPU.h"
float32 x,y;
main()
{
y = rnd_SP_RS(x);
}
