PPT-Dividing a Decimal by a Decimal

Lesson 25 Dividing a Decimal by a Decimal We NEVER want a decimal in the divisor If you have a decimal in the divisor you need to bump it over until it is all the way over to the right of the number. This number representation uses 4 bits to store each digit from 0 to 9 For example 1999 10 0001 1001 1001 1001 in BCD BCD wastes storage space since 4 bits are used to store 10 combinations rather than the maximum possible 16 BCD is often used in b Binary Numbers.
