Globals

In addition to low-level WebAssembly and compiler built-ins, the following global constants and functions are present alongside the standard library's classes.

Constants

```
const NaN: auto // f32 or f64
```
Not a number as a 32-bit or 64-bit float depending on context. Compiles to a constant.
```
const Infinity: auto // f32 or f64
```
Positive infinity as a 32-bit or 64-bit float depending on context. Compiles to a constant.

Functions

```
function isNaN<T>(value: T): bool
```
Tests if a 32-bit or 64-bit float is NaN.
```
function isFinite<T>(value: T): bool
```
Tests if a 32-bit or 64-bit float is finite, that is not NaN or +/-Infinity.
```
function parseInt(str: string, radix?: i32): i64
```
Parses a string to a 64-bit integer. Returns 0 on invalid inputs.
```
function parseFloat(str: string): f64
```
Parses a string to a 64-bit float. Returns NaN on invalid inputs.
