fx64c FX_CosFx64c( fx32 rad );
This function receives radians as an fx32 type and returns the result as fx64c. Accuracy is to at least 7 decimal places and usually to 8 decimal places. Approximations are made using internal progressive calculations. Use this function when the accuracy with FX_CosIdx will be insufficient.
