-/**

- * @defgroup sin Sine

- *

- * Computes the trigonometric sine function using a combination of table lookup

- * and linear interpolation.  There are separate functions for

- * Q15, Q31, and floating-point data types.

- * The input to the floating-point version is in radians and in the range [0 2*pi) while the

- * fixed-point Q15 and Q31 have a scaled input with the range

- * [0 +0.9999] mapping to [0 2*pi).  The fixed-point range is chosen so that a

- * value of 2*pi wraps around to 0.

- *

- * The implementation is based on table lookup using 256 values together with linear interpolation.

- * The steps used are:

- *  -# Calculation of the nearest integer table index

- *  -# Compute the fractional portion (fract) of the table index.

- *  -# The final result equals <code>(1.0f-fract)*a + fract*b;</code>

- *

- * where

- * <pre>

- *    b=Table[index+0];

- *    c=Table[index+1];

- * </pre>
