Functions

exp()

Return Euler's constant (e) raised to the power of a value.

exp(string|int|float $value) : string

This helper wraps the ArangoDB AQL function EXP(value) which returns Euler's constant (approximately 2.71828) raised to the power of the given value. This is the inverse of the natural logarithm function.

Example AQL usage:

EXP(0)                        // returns 1
EXP(1)                        // returns 2.718281828459045 (e)
EXP(2)                        // returns 7.38905609893065 (e²)
EXP(-1)                       // returns 0.36787944117144233 (1/e)
Parameters
$value : string|int|float

The exponent value.
