Exercise 4 - Floating-point Number Comparison Add a new class to the Lab2 project called FloatEqu. This should implement a program that performs the following: a) Declare a double variable and initialize it to (1.0/10) * (1.0/10) Declare another double variable and initialize it to (1.0/100) Insert an if . else statement and print out "EQUAL" if both variables are equal (use ==) and "NOT EQUAL" otherwise. Run the program and check the output. Is it what you would expect? b) Modify the program by adding an if . else statement to determine if the variables are approximately equal, using the approach discussed in the lecture. That is, take the absolute value of the difference between the two numbers, and check if it is lower than the TOLARANCE value (some very small number). The TOLARANCE should be a constant set at the beginning of the program, like this: final double TOLARANCE = 0.000001; The keywordfinal makes it a constant, which means Java will make sure we don't accidentally change the value. Note: to take the absolute value of a number, use Math.abs ()
