48 * HUGE for the VAX and Tahoe converts to the largest possible F-float value.
49 * This implies an understanding of the conversion behavior of atof(3). It
50 * was defined to be the largest float so that overflow didn't occur when it
51 * was assigned to a single precision number. HUGE_VAL is strongly preferred.
