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.

module : java Question 1: (40 MARKS) E-Hailing Bicycle Management System Case Study:An e-hailing company that rents out bicycles needs a system to manage its bicycles, users, and borrowing process. Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles). The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles. Requirements: Add and View Bicycles: Borrow Bicycles: Return Bicycles Display Borrowed Bicycles and Search for a bicycle Create a menu-driven program to implement the above.
