DUDS_UNIT_VALUE

#define DUDS_UNIT_VALUE	(		A,
			cd,
			K,
			kg,
			m,
			mol,
			s,
			rad,
			sr
	)

Value:

(((A) & 0xF) | (((cd) & 0xF) << 4) | (((K) & 0xF) << 8) | \
    (((kg) & 0xF) << 12) | (((m) & 0xF) << 16) | (((mol) & 0xF) << 20) | \
    (((s) & 0xF) << 24) | (((rad) & 3) << 28) | (((sr) & 3) << 30))

Creates the internal value used by duds::Unit in a way that allows the compiler to generate a constant value.

The Unit constructor that takes the same set of parameters cannot be declared as constexpr, but using this macro along with duds::Unit::Unit(std::int32_t) makes a constant when all the macro's parameters are constants.

Parameters

A	The exponent for amperes.
cd	The exponent for candelas.
K	The exponent for kelvin.
kg	The exponent for kilograms.
m	The exponent for meters.
mol	The exponent for moles.
s	The exponent for seconds.
rad	The exponent for radians.
sr	The exponent for steradians.
