# FractionalPart property

Project: Fractions

Unit: DelphiDabbler.Lib.Fractions

Record: TFraction

Applies to: ~>0.1

``````property FractionalPart: TFraction;
``````

## Description

This property provides the fractional part of a TFraction when viewed as a mixed fraction. The fractional part is always a proper fraction, i.e. its absolute value is less than 1.

For any TFraction itâ€™s WholeNumberPart plus its FractionalPart is equal to the original fraction. I.e. for TFraction F

``````F = F.WholeNumberPart + F.FractionalPart;
``````

### Example

``````var
F: TFraction;
begin
F := TFraction.Create(21, 4);
Assert((F.FractionalPart.Numerator = 1)      // 21/4 = 5 + 1/4
and (F.FractionalPart.Denominator = 4));
F := TFraction.Create(-21, 4);
Assert((F.FractionalPart.Numerator = -1)     // -21/4 = -5 + -1/4
and (F.FractionalPart.Denominator = 4));
F := TFraction.Create(5, 11);
Assert((F.FractionalPart.Numerator = 5)      // 5/11 = 0 + 5/11
and (F.FractionalPart.Denominator = 11));
F := TFraction.Create(60, 6);
Assert((F.FractionalPart.Numerator = 0)      // 60/6 = 6 + 0/6
and (F.FractionalPart.Denominator = 6));
F := -7;
Assert((F.FractionalPart.Numerator = 0)      // // -7/1 = -7 + 0/1
and (F.FractionalPart.Denominator = 1));
end;
