input range is [0..2Pi]
* 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 while the
+ * 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.
