    num: N,

    "> -2^32": true;

    },
> & RelaxedExclude<N, 0 | NegativeIndex<1024>>
Type guard that checks if a number is positive (greater than zero).

When this function returns true, TypeScript narrows the type to exclude zero and negative values. This is particularly useful for validating inputs that must be strictly positive, such as dimensions, counts, or rates.
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 & {
    "!=0": true;
    "> -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, 0 | NegativeIndex<1024>>
true if the number is > 0, false otherwise
Example
```
const amount = 42;

if (Num.isPositive(amount)) {
  assert.isTrue(amount > 0);
}

assert.isFalse(Num.isPositive(0));
```
