function Reciprocal: TFraction;
This method returns the reciprocal of the fraction. The fraction must not be zero, i.e. it must have a non-zero numerator.
The reciprocal of fraction
Because the reciprocal of any non-zero number
N is defined as
1/N, applying Reciprocal to a fraction is the same as dividing the fraction into 1. I.e. if F is any TFraction instance with a non-zero numerator,
F.Reciprocal = 1/F;
var F, G, H: TFraction; begin F := TFraction.Create(5, 12); G := F.Reciprocal; H := 1 / F; // see Note Assert(G = H); Assert((G.Numerator = F.Denominator) and (G.Denominator = F.Numerator)); end;
