Hola

Tengo el siguiente problema con la funcion round.
El programa.

/***** round.c *****/
#include <stdio.h>
#include <math.h>

int main ()
{
	double x = 1.234, y;
	y = round(x);
	printf("El valor redondeado de %f es %f.\n", x,y);
	return 0;
}
/***** end ****/
				
Compilacion:
$ gcc -o round -Wall -lm round.c
round.c: In function `main':
round.c:7: warning: implicit declaration of function `round'

* Ejecucion:
$ ./round
El valor redondeado de 1.234000 es -927530976.000000.

$ gcc --version
gcc (GCC) 3.3.5 (Debian 1:3.3.5-3)
[...]

No cacho que estoy haciendo mal... Alguna idea?

Saludos!
