try t1 = SetPrecision[39383738378094852309445543850343.49494, 37] -----Ursprüngliche Nachricht----- Von: steve_H [mailto:nma124 at hotmail.com] Gesendet: Samstag, 20.

Mathematica 5.0 hello; Mathematica 5.0, student version, on XP home edition: t1 = 39383738378094852309445543850343.49494 {c, d} = RealDigits[t1]; now c is {3, 9, 3, 8, 3, 7, 3, 8, 3, 7, 8, 0, 9, 4, 8, 5, 2, 3, 0, 9, 4, 4, 5, 5, 4, 3, 8, 5, 0, 3, 4, 3, 4, 9, 4, 9} notice that I typed in the last digits of t1 as '.49494', i.e the number to the right of the decimal point. But 'c' above is missing the last digit, it only reports '4,9,4,9' instead of '4,9,4,9,4' What happened to the last digit '4' ?
