The sine of a floating point number. |
define external float function FP_sin value float x
A trigonometric function that calculates, in radians, the sine of the floating point number.
Out-of-range values, as in the case of acos() and asin() for |x| > 1, are returned as "not a number" (NaN).
The following sample shows how to use FP_sin to calculate the value of the sin of PI/2. The result is 1.00.
