Ich habe damals diese Frage gestellt und von SImon den von dir aufgeführten Code bekommen. Ich hatte damals auch das gleiche Problem wie du. Du musst, wenn du die Funktion sprintf verwendest neben der fxlib.h auch stdio.h mit einbinden. Dann gehts.

Hab meinen Fehler gefunden, falsches Formatierungszeichen :D

%i int
%c char
%f double, es werden immer 6 Nachkommastellen mit ausgegeben (man kann das verändern indem man hinter dem "%" angibt wieviele Stellen man haben möchte, nach diesem Schema: Vorkommastellen.Nachkommastellen z.B. %8.2f)
%g double, es werden so viele Nachkommastellen angezeigt, wie vorhanden sind

Nur eine kleine Zusammenstellung, mehr dazu hier
