NAME
    IEEESPFix -- convert IEEE single float to integer

SYNOPSIS
    x   = IEEESPFix(  y  );
    d0               d0

    long    x;
    float   y;

FUNCTION
    Convert IEEE single precision argument to a 32 bit signed integer
    and return result.

INPUTS
    y -- IEEE single precision floating point value

RESULT
    if no overflow occured then return
            x -- 32 bit signed integer
    if overflow return largest +- integer
            For round to zero
