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

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

Example AQL usage:

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

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