So, Im making a calc Add In using the SDK.

I'm wondering, How would I display decimals. I know its f, or a g. But I cant seem to get it to work.

Could you guys please give me an example of using sprintf to stick a floating point number into a string. Also how to make it rounded to 2 decimal places.

Thank You.

Hey, here's an example:

float test = 3.14159;
char buffer[20];

Bdisp_AllClr_VRAM();
sprintf(buffer, "%0.2f", test);
PrintMini(1, 1, (unsigned char *)buffer, MINI_OVER);
Bdisp_PutDisp_DD();

You also need to make sure that stdio.h is included:

#include "stdio.h"
