wxLongLong Class Reference

#include <wx/longlong.h>

Detailed Description

This class represents a signed 64 bit long number.

It is implemented using the native 64 bit type where available (machines with 64 bit longs or compilers which have (an analog of) long long type) and uses the emulation code in the other cases which ensures that it is the most efficient solution for working with 64 bit integers independently of the architecture.

Note
This class is obsolete as there are no supported implementations not providing a native 64 bit integer type any longer and the application code can safely use "long long" or "std::int64_t" directly instead of using this class.

wxLongLong defines all usual arithmetic operations such as addition, subtraction, bitwise shifts and logical operations as well as multiplication and division (not yet for the machines without native long long). It also has operators for implicit construction from and conversion to the native long long type if it exists and long.

You would usually use this type in exactly the same manner as any other (built-in) arithmetic type. Note that wxLongLong is a signed type, if you want unsigned values use wxULongLong which has almost exactly the same API as wxLongLong.

If a native (i.e. supported directly by the compiler) 64 bit integer type was found to exist, wxLongLong_t macro will be defined to correspond to it. Also, in this case only, two additional macros will be defined:

Constructor & Destructor Documentation

wxLongLong::wxLongLong ( )

Default constructor initializes the object to 0.

wxLongLong::wxLongLong ( wxLongLong_t  ll)

Member Function Documentation

wxLongLong wxLongLong::Abs ( ) const

Returns an absolute value of wxLongLong - either making a copy (const version) or modifying it in place (the second one).

wxLongLong& wxLongLong::Abs ( )

Returns an absolute value of wxLongLong - either making a copy (const version) or modifying it in place (the second one).

wxLongLong wxLongLong::Assign ( double  d)

This allows to convert a double value to wxLongLong type.

Such conversion is not always possible in which case the result will be silently truncated in a platform-dependent way.

long wxLongLong::GetHi ( ) const

Returns the high 32 bits of 64 bit integer.

unsigned long wxLongLong::GetLo ( ) const

Returns the low 32 bits of 64 bit integer.

wxLongLong_t wxLongLong::GetValue ( ) const

Convert to native long long (only for compilers supporting it).

wxLongLong wxLongLong::operator+ ( const wxLongLong ll) const

Adds 2 wxLongLongs together and returns the result.

wxLongLong& wxLongLong::operator+ ( const wxLongLong ll)

Add another wxLongLong to this one.

wxLongLong wxLongLong::operator++ ( )

Pre/post increment operator.

wxLongLong wxLongLong::operator++ ( int  )

Pre/post increment operator.

wxLongLong wxLongLong::operator- ( const wxLongLong ll) const

Subtracts 2 wxLongLongs and returns the result.

wxLongLong& wxLongLong::operator- ( const wxLongLong ll)

Subtracts another wxLongLong from this one.

wxLongLong wxLongLong::operator- ( ) const

Returns the value of this wxLongLong with opposite sign.

wxLongLong wxLongLong::operator-- ( )

Pre/post decrement operator.

wxLongLong wxLongLong::operator-- ( int  )

Pre/post decrement operator.

wxLongLong& wxLongLong::operator= ( const wxULongLong ll)

Assignment operator from unsigned long long.

The sign bit will be copied too.

Since
2.7.0
wxLongLong& wxLongLong::operator= ( wxLongLong_t  ll)

Assignment operator from native long long (only for compilers supporting it).

wxLongLong& wxLongLong::operator= ( wxULongLong_t  ll)

Assignment operator from native unsigned long long (only for compilers supporting it).

Since
2.7.0
wxLongLong& wxLongLong::operator= ( long  l)

Assignment operator from long.

Since
2.7.0
wxLongLong& wxLongLong::operator= ( unsigned long  l)

Assignment operator from unsigned long.

Since
2.7.0
double wxLongLong::ToDouble ( ) const

Returns the value as double.

long wxLongLong::ToLong ( ) const

Truncate wxLongLong to long.

If the conversion loses data (i.e. the wxLongLong value is outside the range of built-in long type), an assert will be triggered in debug mode.

wxString wxLongLong::ToString ( ) const

Returns the string representation of a wxLongLong.
