Detailed Description

template<size_t n>
struct atlas::bitset::BaseSize< n >

The class BaseSize computes (with its member 'value') the base size.

• the number of words needed for a BitSet holding n bits. Since n must be a compile time constant, BaseSize<n>::value will be one as well.

Essentially we must divide n by longBits, but the fractional result must be rounded up to the next integer; this is achieved by adding constants::posBits=longBits-1 to n before performing the division. Code simplified by MvL.
