Safe, moderate-power math expression evaluation.
Example 1: basic math
2 ^ (log2($m) + x)
Example 2: vectors
sum([1, 2]) + sin([2, 3]) + 4 + min($vector) + dot($vector, $vector)
Example 3: logical operators
$vector > 5 && $vector == $vector
Example 4: any, all, and none
any($vector > 5)
Example 5: NaN
if(sum($vector) > 5? 5 : NaN)
Example 6: implicit NaN
if(sum($vector) > 5? 5)
Example 7: statistics
percentile($vector, 95)
Example 7: random variable
if (sample_unif(-100, 100) > $mine? 1 : 0)
Example 8: statistical test
$mine = [-55, 22, 144]
$mean = 0
$std = 50
count(sample_norm:100($mean, $std) > $mine))
