0.1 + 0.2 == 0.3 -> false 0.1 + 0.2 -> 0.30000000000000004 Why does this happen?
Is this defined by the language? Is there a defined maximum? Is it different in different browsers?
I'm trying to write a Java routine to evaluate simple math expressions from String values like: "5+3" "10-40" "10*3" I want to avoid a lot of if-then-else statements. How can I do this?
Given two date ranges, what is the simplest or most efficient way to determine whether the two date ranges overlap? As an example, suppose we have ranges denoted by DateTime variables StartDate1 to E...

How do I calculate the distance between two points specified by latitude and longitude? For clarification, I'd like the distance in kilometers; the points use the WGS84 system and I'd like to underst...
This is the best algorithm I could come up. def get_primes(n): numbers = set(range(n, 1, -1)) primes =  while numbers: p = numbers.pop() primes.append(p) numbers...
The one thing that has always hindered me from doing 3D programming is failing to understand how math works. I can go along with math fine in programming flow using methods and functions, then its all...
There have been several questions posted to SO about floating-point representation. For example, the decimal number 0.1 doesn't have an exact binary representation, so it's dangerous to use the == ope...
For example, int result; result = 125/100; or result = 43/100; Will result always be the floor of the division? What is the defined behavior?
