Detailed Description

Class to format numbers in an engineering-type form.

Instead of printing numerical powers of 10, we print 'K' (kilo), 'M' (mega), 'm' (milli), 'u' (micro), et. al.

Example:

uint32_t v = 123456; std::cout << Dwm::EngFormat(v) << std::endl;

would print:

123.5K

precision is the maximum precision (places including those to the left of the decimal point) to print. width is the minimum field width to print; we right-justify and fill with spaces.
