float sin517 (
  float x);      /* value to calculate sine for */

The sin517 function calculates the sine of the floating-point value x. The value of x must be in the range ±2^32 (±4294967296.0). Outside this value range an NaN error is returned.

Note

• This routine uses the arithmetic unit of the Infineon C517x/C509 to provide accelerated execution speed. Do not use this routine with a CPU that does not support this feature.

The sin517 function returns the sine of x.
