Javafx - de decimal para ordinais

Não sei o que era mais difícil
suportar a professora de matemática,
ou decorar estes números em ordinais.
Ela me dava umas broncas e saia rindo
da bagunça que eu escrevia no caderno.
A megera ainda fazia questão de lançar
isto nos dias de provas, bimestrais.
Mas mesmo assim ainda sinto saudades
destes tempos, pena que não voltará
nunca mais.
Nunca imaginei que no futuro criaria
um programinha para resolver estas
questões tão simples hoje e que me
torturava tanto no passado.
Compile meu programa, e se você já está
num nível mais avançado fique a vontade
para expandir, modificar e editar de
acordo com seus conhecimentos.

 Veja abaixo uma imagem do programa em execução:

 

 Veja abaixo o código do programa:
