cos(float x)
cosv(var x)
Cosine function.Parameters:
x -
angle in degrees
(cosv) or radians (cos).
Returns:
Cosine of angle x.
Speed:
Fast
Remarks:
-
For maintaining compatibility both to standard-C and to the old C-Script language, the cos function is overloaded under lite-C. When called with a var or int argument, it behaves like cosv(), using degrees; when called with a float or double argument, it behaves like the standard C/C++ cos() function, using radians. For enforcing the use of radians regardless of the argument type, use the (float) cast operator.
-
For learning about trigonometric functions see Trigonometry.
Example:
x = cosv(90); // x is 0
x = cosv(45); // x is 0.707
x = acosv(0.707); // x is 45
