  49 .SH DESCRIPTION
  50 These functions return the value of 10
  51 raised to the power of
  52 .IR x .
  53 .SH RETURN VALUE
  54 On success, these functions return the base-10 exponential value of
  55 .IR x .

  57 For various special cases, including the handling of infinity and NaN,
  58 as well as overflows and underflows, see
  59 .BR exp (3).
  60 .SH ERRORS
