7. What is integer division and how is it different then floating point division?
Floating point division works like normal division, there has to be a decimal involed
for example 7.0/4 = 1.75, In integer division 7/4 = 1 R3 and the R3 is discarded.
8. What is modulus?
- Modulus is an operator that computes the remainder of a division. 7 % 4 = 3.
