No. When you're dealing with decimals, floating point rounding isn't a simple truncation: >>> 1234567890.999999999 1234567891.0 nor is it a rounding: >>> 1234567890.111111111 1234567890.1111112 The former is particularly bad, since POSIX deals with legacy functions by ignoring the nanosecond part, not by rounding it. -- Ciaran McCreesh
