You need to read up on float/double representation in the computer: http://docs.sun.com/source/806-3568/ncg_goldberg.html You should note that 0.1 is *not* representable exactly when using IEEE-standard representation. You should *never* compare two floats/doubles for equality. Instead, always to this: if (abs(x - y) < epsilon) ... Or, in the case of your program: while (1.e-10 < i) { ... } Also note that 'i' is ideomatically used as an *integer* index. Use 'd' or some descriptive name instead.
