carl::exp
Interval< Number > exp(const Interval< Number > &i)
Definition: Exponential.h:10
carl::div
Interval< Number > div(const Interval< Number > &_lhs, const Interval< Number > &_rhs)
Implements the division which assumes that there is no remainder.
Definition: Interval.h:1476
carl::pow
Interval< Number > pow(const Interval< Number > &i, Integer exp)
Definition: Power.h:11
carl::is_one
bool is_one(const Interval< Number > &i)
Check if this interval is a point-interval containing 1.
