There isn't an isPositive method... or is that the point?

!isNegative(n)

from bignumber.js.

I saw isPositive in the code, but it turns out is for another library in the repo.

!isNegative isn't the same as isPositive because you have to check for zero also. So yes, I think it is worth adding isPositive; it helps the readability of my code. Otherwise I will probably end up setting it on BigNumber.prototype which I'd prefer not to do.

To check if a number is positive, as in 'greater than or equal to zero',

n.greaterThanOrEqualTo(0)
n.gte(0)

To check if a number is positive as in 'greater than zero'

n.greaterThan(0)
n.gt(0)

I don't want to add an isPositive method at this time.
