Name
acos()
Description
The inverse of cos(), returns the arc cosine of a value. This function expects the values in the range of -1 to 1 and values are returned in the range 0 to PI (3.1415927).
Examples
float a = PI; float c = cos(a); float ac = acos(c); // Prints "3.1415927 : -1.0 : 3.1415927" println(a + " : " + c + " : " + ac);float a = PI + PI/4.0; float c = cos(a); float ac = acos(c); // Prints "3.926991 : -0.70710665 : 2.3561943" println(a + " : " + c + " : " + ac);
Syntax
acos(value)
Parameters
value(float)the value whose arc cosine is to be returned
