shz_sincos_t

typedef struct shz_sincos {
    float sin;  //!< sinf() approximation for the angle
    float cos;  //!< cosf() approximation for the angle
} shz_sincos_t;

Pair representing the sine and cosine of a given angle.

Fields

Field	Type	Description
sin	float	sinf() approximation for the angle
cos	float	cosf() approximation for the angle

Details

The SH4 provides a single instruction, FSCA, for retrieving fast approximations of both the sine and cosine of a given angle. As such, when you need both values, it's most efficient to grab them both at once as a pair using this structure than it is to retrieve them separately.
