Positive numbers

A positive number is any number greater than 0 (0 is neither positive or negative). Positive numbers may be written with the positive sign (+). A nonzero number written without a sign is also considered positive.

A positive integer on the other hand, is a number that can be written without a fractional component that is greater than 0.
