Not just Germany. Comma vs dot is just a big mess with some countries using both[1]. Even in Germany, which is decimal comma country, the dot is ubiquitous in science and technology publications. Best thing is to stick with dot and us neither comma nor dot as thousands separator but a thin, fixed space. This also what NIST recommends[2]: > #16 Digit spacing > The digits of numerical values having more than four digits on either side of the decimal marker are separated into groups of three using a thin, fixed space counting from both the left and right of the decimal marker. Commas are not used to separate digits into groups of three.
