Gecode::Limits::Int Namespace Reference

---

Detailed Description

Numerical limits for integer variables.

The integer limits are chosen such that addition and subtraction of two values within the limits can be done safely without numerical overflow. Also, changing the sign is always possible without overflow.

Variables
const int	int_max = ((INT_MAX)>>1) - 1
	Largest allowed integer value.
const int	int_min = -int_max
	Smallest allowed integer value.
const double	double_max = 9007199254740991.0
	Largest double that can exactly be represented.
const double	double_min = -9007199254740991.0
	Smallest double that can exactly be represented.
