Round Number

[Marcos Jose Setim]

Hello,

I need to round one number in language C, but I did not obtain. I
already tried to use the:

#include <math.h>

ceil(value);

But it's shown one error:

marcos@zeus:~$ gcc quadradomagico. c
/tmp/ccaZ4Pkk.o(.tex t+0x18d): In function `Gerar_Quadrado ':
: undefined reference to `ceil'
collect2: ld returned 1 exit status

:'(

Any Idea?

Thank's

Marcos

"Undefined reference" errors are typically caused by not linking with
a required library (in this case the "math library").

Use -lm to include it.

$ gcc quadradomagico. c -lm
