Companion Guide	Flip Programming Guide: Writing a Flip Class Part 1

Overview

The Float64 class implements a Flip value type holding a 64 bits floating point value. The following sections will only document the public API.

Sets the value at post construction stage.

virtual void   ctor (ohm::flip::Args & args);
void           ctor (ohm::archi::Float64 val);

The first version sets the value from a cascaded arguments object ohm::flip::Args

Sets the value.

Float64 &      operator = (ohm::archi::Float64 val);

Returns a reference to this .

Returns the value of this .

               operator ohm::archi::Float64 () const;

WARNING:it is invalid to call this function when the object is being restored

Returns the old value of this .

ohm::archi::Float64
               get_old_value () const;

WARNING:it is invalid to call this function when the object is being inited

Returns true if the right handed value is equal to this , false otherwise.

               operator == (ohm::archi::Float64 val) const;
               operator == (const Float64 &other) const;

Returns true if the right handed value is not equal to this , false otherwise.

               operator != (ohm::archi::Float64 val) const;
               operator != (const Float64 &other) const;

Returns true if the old value is different from the current value.

bool           did_value_change () const;

Note:Outside of an observer document_changed call, this will always return false
