Get real number from textfield input

[Naveg]

How do I get real number input from a textfield? Is there a way to change the type of data for the field?

Our teacher told us to do that and he didn't teach us about intreal() and strreal() lolz. Oh geese he was a cracker.

well all you have to do is use turing help . Basically lets say you have two variables
a : int
b : string
lets say a = 10 all you have to do is go
b := intstr (a)
b is now equal to a (or you can do it viceversa or real to string etc.)

Also of use are the strintok() and strrealok() functions, just to make sure your program won't eat itself when the user enters something stpud like "zr7" as an integer.
