Function Documentation

is_positive()

template<typename T >

boost::logic::tribool til::fuzzy::is_positive ( T  x, T  delta = 128 *std::numeric_limits< T >::epsilon()  )

inline

Tests whether x is positive, with a +- delta uncertainty cushion.

In other words: if x > delta, x is definitely positive, and the result is true if x < -delta, x is definitely negative, and the result is false otherwise, the result is indeterminate.

same_sign()

template<typename T >

boost::logic::tribool til::fuzzy::same_sign ( T  x, T  y, T  delta = 128 *std::numeric_limits< T >::epsilon()  )

inline

Returns true iff both arguments have same sign, allowing some degree of imprecision.
