class CTBigint

Description

The CTBigint class represents big integer objects. Big integer objects are 64-bit integers.

Preconditions

This is one of the basic objects from the c-tree database layer.

CTBigint& operator /(const CTBigint& left, const CTBigint& right)

Parameters

• value: [in] long, double, CTBIGINT, CTMoney or CTString value or object to be assigned to or updated with the new CTBigint object.
• left: [in] The left CTBigint object to be concatenated to form the new CTBigint object
• right: [in] The right CTBigint object to be concatenated to form the new CTBigint object

Description

Assigns or concatenates values to form a CTBigint object

Return

The new CTBigint object

CTBigint::operator <, <=, >, >=, ==, !=

Syntax

CTBOOL operator < (const CTBigint& left, const CTBigint& right)
CTBOOL operator <= (const CTBigint& left, const CTBigint& right)
CTBOOL operator > (const CTBigint& left, const CTBigint& right)
CTBOOL operator >= (const CTBigint& left, const CTBigint& right)
CTBOOL operator == (const CTBigint& left, const CTBigint& right)
CTBOOL operator != (const CTBigint& left, const CTBigint& right)

Parameters

• left: [in] The left CTBigint object to be compared
• right: [in] The right CTBigint object to be compared

Description

These overloaded operators make comparisons between the CTBigint objects.

Return

The operators return YES or NO, depending on the result of the comparison.
