Parameters/Return Value

Parameter Data Type Description
value Float the value, from range -1 to +1, to take the arccos of
Return Float acos(value)

Detailed Description

The acos() function returns the arccos of the supplied value within the range of -1 to +1. If you want to return an angle in degrees you can use toDegrees(acos(value))

Examples

Example Result Notes
toDegrees(acos(1/2)); 90
toDegrees(acos(sqrt(2)/2)); 45
toDegrees(acos(sqrt(3)/2)); 30
toDegrees(acos(2)); nan
