That's possible because the significant digits are stored separately from the exponent of the number (which goes approximately from 10^-308 to 10^+308). Thus 5., followed by the rest of the digits, times 10^-19 can be distinguished from zero, despite the same number "vanishes" when subtracted from 1. If this answers the wrong "why", could you please rephrase the question? -- Best regards, Ivan
