## Namespaces

IMP
Base functionality and abstract base classes for representation, scoring and sampling.

IMP::algebra
General purpose algebraic and geometric methods that are expected to be used by a wide variety of IMP modules.

## Functions

bool IMP::algebra::get_are_almost_equal (const double a, const double b, const double epsilon)
Compare two values for "almost equal" (intended for doubles) More...

double IMP::algebra::get_closer_power_of_2 (double x)
Closest power of 2 for a number, not necessarily higher. More...

template<typename T >
IMP::algebra::get_constrained (const T x, const T x0, const T xF)
Constrain a value between two given limits. More...

float IMP::algebra::get_next_larger_power_of_2 (float x)
Closest power of 2 that can contain a number x. More...

double IMP::algebra::get_next_larger_power_of_2 (double x)
Closest power of 2 that can contain a number x. More...

template<typename T >
int IMP::algebra::get_rounded (const T &x)
Rounds a number to next integer. More...

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. More...

double IMP::algebra::get_squared (double x)
