     The exp function returns the exponential function of its floating-
     point argument <x>.
 
     The expl function uses an 80-bit long double form of arguments
     and return values. In all other respects, it is identical to the
     regular function.
 
     Return Value
 
     These functions return e^x. The functions return HUGE_VAL on
     overflow and set errno to ERANGE; on underflow, they return 0 but
     do not set errno.
