Function toNearest

toNearest(
    this: number,
    interval?: number,
    method?: "round" | "ceil" | "floor",
    base?: number,
): number
Round a number to the closest number which substracted from the base is a multiple of the provided interval. This is a convenience function intended to humanize issues of floating point precision. The interval is treated as a standard string representation to determine the amount of decimal truncation applied.
Parameters
- this: number
- interval: number = 1
  The step interval
- Optionalmethod: "round" | "ceil" | "floor" = "round"
  The rounding method
- Optionalbase: number = 0
  The step base
Returns number
The rounded number
Example: Round a number to the nearest step interval
```
let n = 17.18;
n.toNearest(5); // 15
n.toNearest(10); // 20
n.toNearest(10, "floor"); // 10
n.toNearest(10, "ceil"); // 20
n.toNearest(0.25); // 17.25
n.toNearest(2, "round", 1); // 17
