| /* long __fixsfsi (float A); |
| The __fixsfsi() function converts A to the integer value. No rounding, |
| the fractional is losted. The compiler calls this function to perform |
| a cast operation from float (i.e. double) to long. No saturation. |
| |
| Return: |
| The integral part of A. If A is too big (i.e. A is less then |
| -0x0.ffffffp+31 or A is great then +0x0.ffffffp+31), this realization |
| returns the LONG_MIN value (i.e. 0x80000000). If A is not a number, |
| also LONG_MIN is returned. |
| |
| See '__fixunssfsi.S' why saturation is't used. |
