Detailed Description

template<typename NUM>
struct cosmos::HexNum< NUM >

Helper to output a primitive integer as hexadecimal in the style of 0x1234.

The stream state will be maintained i.e. after the output operation is finished the previous/default stream state will be applied

Leading zeroes will be added to reach the desired field width.

The given field width will only count towards the actual digits the number consists of. A possible base prefix is not counted towards the field width. I.e. if showBase() is set to true then HexNum(0x10, 4) will be printed as: "0x0010".
