Project: Fractions

Unit: DelphiDabbler.Lib.Fractions

Record: TFraction

Applies to: ~>0.1

``````class operator IntDivide(const A, B: TFraction): Int64;
``````

## Description

This operator overload permits an integer division to be performed on TFractions using the `div` operator.

The result of the operation is the largest whole number less or equal to the result of dividing A by B.

One of the operands may be either an integer or floating point value. The Implicit operator takes care of converting the integer and floating point operands to a TFraction before performing the integer division.

The second operand must not be zero. In the case of a TFraction this means the Numerator must not be zero.

### Example

``````var
F1, F2: TFraction;
begin
// 7/8 div 1/3 = Trunc(7/8 * 3/1) = Trunc(21/8) = 2
F1 := TFraction.Create(7, 8);
F2 := TFraction.Create(1, 3);
Assert(F1 div F2 = 2);

// 2/3 div 2/3 = Trunc(2/3 * 3/2) = Trunc(6/6) = 1
F1 := TFraction.Create(2, 3);
F2 := TFraction.Create(2, 3);
Assert(F1 div F2 = 1);

// 5 div 2/3 = Trunc(5/1 * 3/2) = Trunc(15/2) = 7
F2 := TFraction.Create(2, 3);
Assert(5 div F2 = 7);

// 10/3 div 1 = Trunc(10/3 * 1/1) = Trunc(10/3) = 3
F1 := TFraction.Create(10, 3);
Assert(F1 div 1 = 3);
end;
