 FLOATING POINT MATH   Floating point math causes two major errors in computer science: the "floating point" math error and "penny error" problem.   A "floating point math error" in computer science refers to inaccuracies that occur when performing calculations with real numbers on a computer due to the limitations of how computers store decimal values. The "penny error" problem occurs when adding lots of currency values together.   This is also common in probability math. Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes).    LIMITATIONS 1) Computers have limited storage limits, while some fractions are unlimited like 1/3. Computers just round the last digit it can hold. 2) Computers have limits to screen display size.  Super long numbers get chopped off on screens or when stored. Especially common back in the days of calculators. 3) A decimal fraction like 0.1 (which is 1/10) has an infinite repeating binary repr...
