defect in a numerical algorithm			defect
ordering operations poorly so errors build up	if a numerical application is designed to work with floating-point numbers, then make sure it works with inputs that vary widely in magnitude, including both large positive and large negative exponents pay particular attention to the accuracy of the result when a floating point value is being repeatedly decremented or incremented by small amounts	when you do small operations on large floating point numbers, and excessive rounding or truncation errors build up	defect in a numerical algorithm
