Detailed Description

template<typename T, typename UT>
struct ThePEG::OUnitErr< T, UT >

OUnitErr is used to write out unitful numbers with an error estimate on a standard ostream.

using the helper function ouniterr an energy e with an error estimate de can be written out as eg. cout << ouniterr(e, de, GeV);. The result will be presented in scientific format (with the exponent divisible by three) with the relevant number of significant digits with a single digit in parenthesis indicating the error in the least significant digit, eg. 1.23(2)e+03.
