Function Documentation

double DegToRad

(

double

num

)

Convert degrees to radians.

Parameters:

num

number in degrees.

Returns:

number in radians.

double RadToDeg

(

double

num

)

Convert radians to degrees.

Parameters:

num

number in radians.

Returns:

number in degrees.

void SinCos	(	double	Degrees,
		double *	sina,
		double *	cosa
	)

Get the sin and cosine of a number.

The function attempts to use GNU sincos extension when possible. The sin and cosine values for Degrees are stored in the sina and cosa parameters.

Parameters:

	Degrees	the number in degrees to return its sin and cosine.
	sina	pointer to a double to hold the sin value.
	cosa	pointer to a double to hold the cosine value.
