convert string "33.4" to number 33.4

Hello;

Is there some kind of number(string) function that will convert "33.4" to the number 33.4.

If I just set a number variable to the string "33.4" it doesn't work.

Thanks for your time.

float("33.4")

Thanks lots.

you can also use int(33.4) and then to go back str(whatever int)
