fx64c FX_CosFx64c( fx32 rad );
| rad | Radians in fx32-format fixed-point decimal. |
Approximation of the cosine.
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 FX_CosIdx is not sufficiently accurate.
