196 * Let ipart = int(x)
197 * Let fpart = x - ipart;
198 * So, exp2(x) = exp2(ipart) * exp2(fpart)
199 * Compute exp2(ipart) with i << ipart
205 int32_t ipart;
215 ipart = (int32_t) x;
216 fpart = x - (float) ipart;
219 * epart.f = (float) (1 << ipart)
220 * but faster and without integer overflow for ipart > 31
222 epart.i = (ipart + 127 ) << 23;
