in reply to How to use rad2rad

Hello Masayoshi Fujimoto, and welcome to the Monastery!

The function rad2rad is not exported by the Math::Trig module, so to use it you need to put the full module name in front:

my $radians_wrapped_by_2pi = Math::Trig::rad2rad($radians);

Update: Here is an example of rad2rad() in use:

use Modern::Perl; use Math::Trig ':pi'; my $radians = 4.5 * pi; my $radians_wrapped_by_2pi = Math::Trig::rad2rad($radians); say 'rad2rad(', $radians, ') = ', $radians_wrapped_by_2pi;


1:49 >perl rad2rad(14.1371669411541) = 1.5707963267949 1:49 >

Hope that helps,
