Have you got the init_coridium() in there?

Csample showed an example and I just compiled and ran this--

#include "coridium.h"
#include "printf.h"
#include <math.h>

int main(void)
{
int i,j;

init_coridium(); // REQUIRED OPERATION
for (i=0; i<100; i= i+10) {
j = 100*sinf(00.01 * i);
printf("sin(%d/100) = %d/100\n",i,j);
}

while (1);
}

------------------ output ------------------

sin(0/100) = 0/100
sin(10/100) = 9/100
sin(20/100) = 19/100
sin(30/100) = 29/100
sin(40/100) = 38/100
sin(50/100) = 47/100
sin(60/100) = 56/100
sin(70/100) = 64/100
sin(80/100) = 71/100
sin(90/100) = 78/100

It works out of thumb mode, so I'm just going to use that for now.
Thank you...

#include <math> and add "-lm" to the compiler/linker options should do it.

What does the assembly listing show? Try compiling with the option
"-msoft-float" or "-mhard-float".
