Returning values from functions

Hi all! This might seem like a bit of a stupid question, but how do I return REAL values from functions? This is what i've got: e.g. time# = 0.0 Global Ai# = Rnd(-50, 50) / 100 Global Bi# = Rnd(-50, 50) / 100 Print pathX(time) Function pathX(t#) xCoord# = Ai * t^2 + Bi * t Return xCoord# End Function This is just an extract of my code - when I print the value of pathX(time), no matter what time I use I only get integer values. Any help would be greatly appreciated! Thanks!

Problem is in HOW you declare a function: Function PathX(t#) -> will return an integer end function Function PathX%(t#) -> will return an integer Function PathX#(t#) -> will return a float (!) Function PathX$(t#) -> will return a string Function PathX.enemey(t#) -> will return a type If your function is for example called: "Function PathX#(t#)" then it will always return a float! Even if you call the function within your code without the # sign, for example, these two will return the SAME result: return# = PathX(1.2) return# = PathX#(1.2) d.

how about time# = 0.0 Global Ai# = Rnd(-50, 50) / 100 Global Bi# = Rnd(-50, 50) / 100 Value#=pathX(time#) print Value# Function pathX(t#) xCoord# = Ai * t^2 + Bi * t Return xCoord# End Function

Thanks Danny, i forgot about the # after the function name!
