Wiki Markup
The Java language provides two primitive floating-point types, {{float}} and {{double}}, which are associated with the single-precision 32-bit and double-precision 64-bit format values and operations specified by IEEE 754 \[[IEEE 754|AA. Bibliography#IEEE 754 2006]\]. Each of the floating-point types has a fixed, limited number of mantissa bits. Consequently, it is impossible to precisely represent any irrational number (for example, pi). Further, because these types use a binary mantissa, they cannot precisely represent many finite decimal numbers, such as 0.1, because these numbers have repeating binary representations.
