Function numericPercent

numericPercent(
    interval?: number,
    repeating?: boolean,
    start?: number,
    end?: number,
): Generator<number, void, unknown>
Yields numeric range between 0.0-1.0.
```
// Yields: [0, 0.2, 0.4, 0.6, 0.8, 1]
const a = [...numericPercent(0.2)];

// Repeating flag set to true:
for (const v of numericPercent(0.2, true)) {
 // Infinite loop. V loops back to 0 after hitting 1
}
```
If repeating is true, it loops back to 0 after reaching 1
Parameters
- interval: number = 0.01
  Interval (default: 0.01, ie. 1%)
- repeating: boolean = false
  Whether generator should loop (default: false)
- start: number = 0
  Start (default: 0)
- end: number = 1
  End (default: 1)
Returns Generator<number, void, unknown>
