| .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. |
| .PP |
| For a discussion of the errors that can occur for these functions, see |
| .BR exp (3). |
| .SH VERSIONS |
| These functions first appeared in glibc in version 2.1. |
| .SH ATTRIBUTES |

| .SH CONFORMING TO |
| These functions are GNU extensions. |
| .SH BUGS |
| Prior to version 2.19, the glibc implementation of these functions did not set |
| .I errno |
| to |
| .B ERANGE |
| when an underflow error occurred. |
