problem with the ceil command...

[j0hnb]

The ceil command is causeing my program to not compile.. is there another command that would have the same effect. to round a number up to it's next whole #.

What platform, what compiler and what error messages?

I am using my schools complier olympus.. it might be a problem with my command...
years = ceil(years);
the error message was:
/var/tmp/ccLYNv1d.o(.text+0x264): undefined reference to `ceil'

You are not linking the maths libraries in. How you do this depends on the compiler (refer to the manuals) but under gcc it is done with the -lm switch -

gcc -o appname appname.c -lm
