Is there some way with a Printf format string to say this: Printf.sprintf "%03d_%03d_%03d" millions thousands units But, without having to compute millions, thousands and units (as I naively implemented)? I.e. I would like to have a ‘_’ to separate every three digits starting from the right.

[image] UnixJunkie: Is there some way with a Printf format string to say this: Yes, it is documented in the manual: Printf.sprintf "%#d". Cheers, Nicolas
