using a built in function in the module 1

[concino]

i'm trying to learn object oriented approach; when i tried to use ceil function in on of my subroutines it gives me undef function error.

i've a .pm file where i have all my subroutines that belong to a class. in one of these subroutines i tried to use ceil function where i've gotten the error.

so is there anyone out there who knows how to deal with it?

thank you.

ceil() isn't a built-in Perl function. It's part of the POSIX module. Make sure your .pm file has 'use POSIX;' somewhere near the top and refer to the function as POSIX::ceil
