.SH DESCRIPTION
|
2007-04-12 22:42:49 +00:00
|
|
|
The call
|
2006-09-06 12:33:29 +00:00
|
|
|
.I clog10(z)
|
2006-09-06 12:43:19 +00:00
|
|
|
is equivalent to
|
2006-09-07 07:49:22 +00:00
|
|
|
.IR clog(z)/log(10) .
|
2007-04-12 22:42:49 +00:00
|
|
|
The other functions perform the same task for
|
2006-09-06 12:33:29 +00:00
|
|
|
.I float
|
2007-04-12 22:42:49 +00:00
|
|
|
and
|
2006-09-06 12:33:29 +00:00
|
|
|
.IR "long double" .
|
|
|
|
|
|
2007-04-12 22:42:49 +00:00
|
|
|
Note that
|
|
|
|
|
.I z
|
|
|
|
|
close to zero will cause an overflow.
