Was programming and stumbled across this method to prevent divide by 0 errors.

Rather than dividing, simply multiply by the inverse, that is, the quantity raised to the power of -1. In the case of a /0 error, it will simply return 1.#INFF, instead of the error.

Observe:

that the INVERSE of it, meaning the reciprocal (the reciprocal of a fraction in a/b is b/a) if im reading that right

Thats correct smart guy. The first part is to see that the inversion idea WORKS, that is, (5/2)^(-1)=2/5=.4 . The second set is to show that the divide by 0 error, that is (0/5)^(-1)=5/0 doesn't occur.
