Chapter 6, Problem 2RQ

Program Plan Intro

Decimal data type:

• Some programming languages gives a build-in decimal data type to represent non-repeating decimal fractions.
• It could be implemented either a fixed-point number or floating-point number.
  • The denominator would be set to a fixed power of ten in the fixed-point case.
  • A variable exponent would denote the power of ten to which the mantissa of the number is multiplied in the floating-point case.
