3.28 Lab 6b: TestLeapYean Objectives Use decision statements . Employ math methods to convert float to int Condense Boolean tests into one compound Boolean expression using logical operators Task Write a program that reads in a float value between 0.0 and 0.99999, and then displays whether it is a leap year A leap year is an integer greater than 1584 that is either divisible by 400 or is divisible by 4 but not 100. To generate a year between 1800 and 2000, use int. year - Math.round (200*x 1800);1 where x is a float value entered by the user The round ( ) method of the Math class returns the integer nearest the float passed to it. The transformation y=208x+1800 converts a number in the range 0.0 to 1 into a number in the range 1800 to 2000 Choosing test values We must check for a representative value from each of the following Test Value Year 0.345 0.55 0.9999 2000 0.0008 782 1956 Result Not a leap year Not a leap year leap year Not a leap year leap year 0 1869 even, not divisible by 4, 100, or 400 divisible by 400 divisible by 4 and 100, not 400 divisible by 4 not 100 or 400 1910 1800
