`math.acos`

The arccosine of angle, in radians. It is defined for a value from -1 to 1.

math.acos(const float angle) → const float

math.acos(input float angle) → input float

math.acos(series float angle) → series float

math.acos(simple float angle) → simple float

Parameter	Type	Required	Description
`angle`	`const float`	yes	A cosine value from -1 to 1. The contract spells this argument `angle`, though here the angle is the result rather than the value you pass.

Returns const float or input float or series float or simple float — The angle in radians, as a float in the argument’s form.
