-/**
- * @defgroup SinCos Sine Cosine
- *
- * Computes the trigonometric sine and cosine values using a combination of table lookup
- * and linear interpolation.
- * There are separate functions for Q31 and floating-point data types.
- * The input to the floating-point version is in degrees while the
- * fixed-point Q31 have a scaled input with the range
- * [-1 0.9999] mapping to [-180 +180] degrees.
- *
- * 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>.
