.SH DESCRIPTION

These functions return the value of 10

raised to the power of

.IR x .

.SH RETURN VALUE

On success, these functions return the base-10 exponential value of

.IR x .

.PP

For various special cases, including the handling of infinity and NaN,

as well as overflows and underflows, see

.BR exp (3).

.SH ERRORS

See

.BR math_error (7)

for information on how to determine whether an error has occurred

when calling these functions.
