ln3 Method - IsZero, IsNotZero

Description

Determine whether a large number is zero.  These functions are only marginally more efficient than comparing the large number to zero.  They are primarily for backward compatibility with ln2.

Signature

bool IsZero( void ) const
bool IsNotZero( void ) const

Parameters

( none )

Returns

( bool )  true if the large number is zero (not zero); false otherwise.

Example

Check to see if the value in the variable X is zero.  If it is, print out the string X is zero:

ln X; ... if( X.IsZero( ) ) cout << "X is zero" << endl;
