# Thornless

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))

```
