spin_to_state()

template<typename State >

State Aleph::CA::ca_ising_detail::spin_to_state ( int  spin )

inlinenoexcept

Inverse of state_to_spin.

Signed types receive ±1; unsigned types receive 0 for -1 and 1 for +1.

state_to_spin()

template<typename State >

int Aleph::CA::ca_ising_detail::state_to_spin ( const State &  v )

inlinenoexcept

Map any integral state to a spin in {-1, +1}.

Signed types use the sign of the value (zero is treated as +1); unsigned types treat zero as -1 and any non-zero as +1.
