math.h and other included header files

I was trying to write a program in c that used the exp() function in math.h. It wasn't working so I investigated and found a crippled version of math.h that didn't have that function (it was in /usr/include). Also other libraries weren't there (stlib.h, etc,). What's up with that? I did a complete install so basically it isn't included in slackware. Does anybody know how I can get those standard libraries (they're documented in any book on c). The lame math.h file was in the glibc package. Why aren't they included?

Nevermind, I'm an idiot. I'm somewhat new to C and I was trying to convert a matlab script to c. I found the following after doing some more searching.

You have to link with the math library.
(, libm.a, aka -lm)


cc -o foo foo.c -lm
