[Tutor] decimal floating point?

[michel maho]

To all
    I have the following calculation:

    "Je Body Mass Index is",gewicht/lengte**2

    The result is a (digital?)floating point figure with with 10 decimal numbers. For =
    example 27.2345678487
    Did I mis something? I would like to reduce it to one or two decimal =
    numbers.(27.2) but round(_,1) does not work.
    Is there any other way?
    Thank You
    Michel Maho
