std::string mrpt::system::unitsFormat(const double val, int nDecimalDigits = 2, bool middle_space = true)

This function implements formatting with the appropriate SI metric unit prefix: 1e-12->’p’, 1e-9->’n’, 1e-6->’u’, 1e-3->’m’, 1->’’, 1e3->’K’, 1e6->’M’, 1e9->’G’, 1e12->’T’ If the input is exactly 0, it will return the string "0", so the overall result looks like that (e.g. using meter units on the caller side):

13445.0  => 13.44 km
0.0      =>     0 m
