Detailed Description

template<typename Integer>
struct DGtal::functors::LargeTruncationFunctor< Integer >

Binary functor that returns the algebraic quotient i of a/b with any fractional part discarded (truncation toward zero).
Note that \( |i| \leq |a/b| \).

(For a truncation toward negative infinity, see IntegerComputer::floorDiv)

Template Parameters

Integer

a model of integer used to store a and b
