mathematical functions

[GForce Profile]

Hi, is it possible to use functions like sine?
So for example if I wanted the Ycoord of my object to depend on Y = d + a sin bX, with a, b and d controllable parameters and X the variable, to create a regular jump, how would I do that?

With the standard development systems the function

double sin(double d)

should be available.

See Math.h.

Hey thanks, but what I don't understand is, how I need to type this in the SDK.
I know you leave it empty with void, what do you do with double?

This is the description I took from the Hitachi SHC-manual, included in the old SDK:

double sin(double d)
Description: Computes the sine of a floating-point radian value.
Header file: <math.h>
Return values: Sine of d
Parameters: d Radian value for which sine is to be computed

Example:

Code: Select all

#include <math.h>
  double d, ret;
  ret=sin(d);

Ooh thanks, got it! I forgot to do #include "math.h"
