WebLaunch Python. Type 0.1 + 0.2. The answer is 0.30000000000000004. This happens because floating point numbers (the way that computers usually represent fractional numbers) is an approximation rather than an exact value. (Note also that 0.3 != 0.30000000000000004. So essentially 0.1 + 0.2 != 0.3, in floating point arithmetic.
