# Convert method

Project: Fractions

Unit: DelphiDabbler.Lib.Fractions

Record: TFraction

Applies to: ~>0.1

``````function Convert(const Multiplier: Int64): TFraction;
``````

## Description

This method returns a new fraction whose numerator and denominator are integer multiples of the current fraction. The original and new fractions are equivalent.

The Multiplier parameter specifies the multiplier to be applied. Multiplier must be greater than zero.

### Example

``````var
F, FConv: TFraction;
begin
F := TFraction.Create(1, 2);
FConv := F.Convert(6);         1/2 * 6/6 = 6/12
Assert((FConv.Numerator = 6) and (FC.Denominator = 12));
Assert(F = FConv);  // equivalent

F := TFraction.Create(-5, 13); -5/13 * 3 = -15/39
FConv := F.Convert(3);
Assert((FConv.Numerator = -15) and (FC.Denominator = 39));
Assert(F = FConv);

F := 0;
FConv := F.Convert(7);         0/1 * 7/7 = 0/7
Assert((FConv.Numerator = 0) and (FC.Denominator = 7));
Assert(F = FConv);

F := 3;                        3/1 * -3/-3 = -9/-3 = 9/3
FConv := F.Convert(-3);
Assert((FConv.Numerator = 9) and (FC.Denominator = 3));
Assert(F = FConv);
end;
