Number Class operator>=() operator==() operator!=() This method checks whether the first parameter specified is greater than or equal to the second parameter specified. If the first parameter is greater than or equal to the second parameter, then true is returned; otherwise, false is returned. If either parameter is equal to infinity, then false is returned. Syntax bool operator>=(const Number &a, const Number &b); Parameters a, b Numbers which are compared. This method checks whether the parameters specified are equal. If the parameters are equal, then true is returned; otherwise, false is returned. If either parameter is equal to +infinity or -infinity, then false is returned. Syntax bool operator==(const Number &a, const Number &b); Parameters a, b Numbers which are compared. This method checks whether the first parameter specified is equal to the second parameter specified. If the parameters are not equal, true is returned; otherwise, false is returned. Syntax bool operator!=(const Number &a, const Number &b); 8-116 Oracle C++ Call Interface Programmer’s Guide
operator=() operator*=() operator/=() Parameters a, b Numbers which are compared. Number Class This method assigns the value of the parameter specified to the Number object. Syntax Number& operator=(const Number &a); Parameters a The number to be assigned. This method multiplies the Number object by the parameter specified, and assigns the product to the Number object. Syntax Number& operator*=(const Number &a); Parameters a A parameter of type Number. This method divides the Number object by the parameter specified, and assigns the quotient to the Number object.
