Why is this astonishing? The smallest positive single-precision IEEE floating point number is roughly 1.175494e-38. Since user-specified numbers are rounded to the closest representable value, 1.4e-45f is a fancy way of typing zero. Double-precision values have much greater dynamic range; DBL_MIN is roughly 2.225074e-308.
