It's not a problem with Flash--it's a problem with binary numbers. Integers are accurate because all integers are a multiple of 1, and binary does just fine with combining 0's and 1's, the only possibile values of a digit in the binary system. If you think of decimals as fractions, maybe it will help you understand the issue. In binary, a digit can only be a multiple of 2: 1/2, 1/4, 1/8/ 1/16, 1/32, and so on. You can create numbers that aren't multiples of two by adding multiple digits. For example, 1/4 + 1/8 = 3/8, or .375. This works pretty well, until you get numbers with a lot of decimal places. At some point, you will find a decimal that is impossible to make using powers of 2.
