Re: [MacPerl] Trig Trouble

[Rick Gibson <gibson@nyssa.tamu.edu>]

In Math::Trig, there are already deg2rad() and rad2deg() functions.   
For example:

#!/usr/sbin/perl -w

use Math::Trig;

$angle = 30.; # example
$angRad = deg2rad($angle);

print "in degrees, angle=$angle\n";
print "in radians, angle=$angRad\n";
$x = pi;
print "pi is: $x\n";
