+ 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.
