|
||||
* The floating point function also allows values that are out of the usual range. When this happens, the function will
|
||||
* take extra time to adjust the input value to the range of [-180 180].
|
||||
*
|
||||
* The result is accurate to 5 digits after the decimal point.
|
||||
*
|
||||
* The implementation is based on table lookup using 360 values together with linear interpolation.
|
||||
* The steps used are:
|
||||
* -# Calculation of the nearest integer table index.
|
||||
* -# Compute the fractional portion (fract) of the input.
|
||||
* -# Fetch the value corresponding to \c index from sine table to \c y0 and also value from \c index+1 to \c y1.
|
||||
* -# Sine value is computed as <code> *psinVal = y0 + (fract * (y1 - y0))</code>.
|
||||
* -# Fetch the value corresponding to \c index from cosine table to \c y0 and also value from \c index+1 to \c y1.
|
||||
* -# Cosine value is computed as <code> *pcosVal = y0 + (fract * (y1 - y0))</code>.
