| fea681da | 50 | .SH DESCRIPTION |
| 60a90ecd MK |
51 | The |
| 52 | .BR exp10 () | |
| 53 | function returns the value of 10 | |
| fea681da | 54 | raised to the power of \fIx\fP. |
| f4fe98d1 MK |
55 | .SH RETURN VALUE |
| 56 | On success, these functions return the base-10 exponential value of | |
| 57 | .IR x . | |
| 58 | ||
| 59 | For various special cases, including the handling of infinity and NaN, | |
| 60 | as well as overflows and underflows, see | |
| 61 | .BR exp (3). | |
| 62 | .SH ERRORS | |
| 63 | See | |
| 64 | .BR math_error (7) | |
| 65 | for information on how to determine whether an error has occurred | |
| 66 | when calling these functions. | |
| 67 | ||
| 68 | For a discussion of the errors that can occur for these functions, see | |
| 69 | .BR exp (3). | |
| 70 | .\" FIXME . exp10 doesn't give ERANGE for an underflow, unlike exp() and exp2() | |
| 71 | .\" Bug raised: http://sources.redhat.com/bugzilla/show_bug.cgi?id=6787 | |
| fea681da | 72 | .SH "CONFORMING TO" |
