acos(string|int|float $value) : string

This helper wraps the ArangoDB AQL function ACOS(value) which returns the arccosine (inverse cosine) of a value in radians. The value must be between -1 and 1 (inclusive), otherwise it returns null.

Example AQL usage:

ACOS(1)  // returns 0
ACOS(0)  // returns 1.5707963267948966 (π/2)
ACOS(-1) // returns 3.141592653589793 (π)
ACOS(2)  // returns null (out of range)
Parameters
$value : string|int|float

The input value (must be between -1 and 1).
