I don't like having to constantly define my own log10 function. This method is also
rather unoptimized.

perldoc -f log
log EXPR
log Returns the natural logarithm (base e) of EXPR. If
EXPR is omitted, returns log of $_. To get the log
of another base, use basic algebra: The base-N log
of a number is equal to the natural log of that
number divided by the natural log of N. For
example:
sub log10 {
my $n = shift;
return log($n)/log(10);
}
See also "exp" for the inverse operation.

There is an all Perl implementation of log10 in Math::Complex and the standard C math
lib's log10 function is included with the POSIX module. However the POSIX module is
rather large and I think it's a rather in-obvious place to look for a math function.
So I'm proposing a simple module that allows access to the standard C math lib's: log,
log10, exp, and pow functions.
Possible names are:
Math::Log
Math::Logarithm
Math::Logarithmic
...
-J
