- /** CODECS - FIXED POINT MATH ROUTINES - USAGE
- *
- * - x and y arguments are fixed point integers
- * - fracbits is the number of fractional bits in the argument(s)
- * - functions return long fixed point integers with the specified number
- * of fractional bits unless otherwise specified
- *
- * Calculate sin and cos of an angle:
- * fp_sincos(phase, *cos)
- * where phase is a 32 bit unsigned integer with 0 representing 0
- * and 0xFFFFFFFF representing 2*pi, and *cos is the address to
- * a long signed integer. Value returned is a long signed integer
- * from -0x80000000 to 0x7fffffff, representing -1 to 1 respectively.
- * That is, value is a fixed point integer with 31 fractional bits.
- *
- * Take square root of a fixed point number:
- * fp_sqrt(x, fracbits)
- *
