Namespaces
namespace	IMP
	The `IMP` kernel provides base classes and key shared functionality.
namespace	IMP::algebra
	This module contains general purpose algebraic and geometric methods.
Functions
bool	IMP::algebra::get_are_almost_equal (const double a, const double b, const double epsilon)
	Compares two values (intended for doubles).
template<typename T >
T	IMP::algebra::get_constrained (const T x, const T x0, const T xF)
	Constrains a value between two given limits.
double	IMP::algebra::get_next_larger_power_of_2 (double x)
	Closest power of 2 that can contain a number x.
float	IMP::algebra::get_next_larger_power_of_2 (float x)
	Closest power of 2 that can contain a number x.
template<typename T >
int	IMP::algebra::get_rounded (const T &x)
	Rounds a number to next integer.
template<typename T >
int	IMP::algebra::get_sign (const T &x)
	Sign of a number. 1 if the number is higher or equal to 0 and -1 otherwise.
bool	IMP::algebra::xorT (bool x, bool y)
	xor operation between two values
