Say goodbye to the world of common sense, welcome to the world of the Fortran standard! ;-) "The scale factor k controls the decimal normalization (10.3.2, 10.8.5). If −d < k <= 0, the output field contains exactly |k| leading zeros and d − |k| significant digits after the decimal symbol. If 0 < k < d + 2, the output field contains exactly k significant digits to the left of the decimal symbol and d − k + 1 significant digits to the right of the decimal symbol. Other values of k are not permitted."
