Function isNonNegative

isNonNegative<N extends number>(
    num: N,
): num is number & {
    "> -2^16": true;
    "> -2^32": true;
    ">= -2^15": true;
    ">= -2^31": true;
    ">=0": true;
    NaNValue: false;
} & Readonly<
    {
        "TSTypeForgeInternals--edd2f9ce-7ca5-45b0-9d1a-bd61b9b5d9c3": unknown;
    },
> & RelaxedExclude<N, NegativeIndex<1024>>
Type guard that checks if a number is non-negative (greater than or equal to zero).

When this function returns true, TypeScript narrows the type to exclude negative values, which is useful for operations that require non-negative inputs like array indices or measurements.
Type Parameters
- N extends number
  The numeric literal type or number type to check
Parameters
- num: N
  The number to check
Returns num is number & {
    "> -2^16": true;
    "> -2^32": true;
    ">= -2^15": true;
    ">= -2^31": true;
    ">=0": true;
    NaNValue: false;
} & Readonly<
    {
        "TSTypeForgeInternals--edd2f9ce-7ca5-45b0-9d1a-bd61b9b5d9c3": unknown;
    },
> & RelaxedExclude<N, NegativeIndex<1024>>
true if the number is >= 0, false otherwise
Example
```
const candidate = 10;

if (Num.isNonNegative(candidate)) {
  const index: number = candidate;

  assert.isTrue(index === 10);
}

assert.isFalse(Num.isNonNegative(-1));
```
