Function aerospike::expressions::num_log

pub fn num_log(
    num: FilterExpression,
    base: FilterExpression
) -> FilterExpression

Create “log” operator for logarithm of “num” with base “base”. All arguments must resolve to floats. Requires server version 5.6.0+.

// log(a, 2.0) == 4.0
use aerospike::expressions::{eq, float_bin, float_val, num_log};
eq(num_log(float_bin("a".to_string()), float_val(2.0)), float_val(4.0));
