llSin

float llSin(float Theta)

Returns the sine of Theta (Theta in radians).

Parameters
Theta (float)

Due to IEEE 754 floating-point precision, llSin(PI) returns -8.742278E-8 (hex: 0xB3BBBD2E) instead of 0.0. The error is cumulative with multiples of PI. For example, llSin(100000.0*PI) returns 0.015890 when the result should be 0.0.
