Remarks

• cos() is an overloaded function under lite-C. When called with a var argument, it behaves like cosv(); when called with a float or double argument it behaves like the standard C/C++ cos() function.

Example

x = cosv(90); // x is 0
x = cosv(45); // x is 0.707
x = acos((var)0.707); // x is 45
