Should return true if values are equal. | |

Standard_Real | myTolerance |
Class to define basic compare operations. Basic implementation use redirection to standard C++ operators. You can use standard C++ templates mechanisms to redefine these methods or to inherit basic implementation to create multiple comparators for same type with different rules.
