trouble with number rounding

[laurie]

Hello,

I am using a modified version of the "VisualScaleAnalog" script which is recording the position of a muse click on a scale.

Then it displays the recorded "score" to the user.

What the original script does is this

    Dim percent as Integer
    Mouse.GetCursorPos ptPress.X, ptPress.Y
    percent = 100*((ptPress.X-VAS_SliderDummy.Left)/sw)
    ...
    and then it displays "percent"

So the original script would display a score of "75" if the subject clicked on the 3/4th of the scale

What i want to display is something like "7.5" instead of "75".

I tried this :

    Dim percent as Integer
    Dim score as Double
    Mouse.GetCursorPos ptPress.X, ptPress.Y
    percent = 100*((ptPress.X-VAS_SliderDummy.Left)/sw)
    score=CInt(percent)/10
    ...
    and then display "score"

but then it would display something like "7.500121245" instead of just "7.5"
how can i format the score so that it shows to 1 or 2 decimal places?

thank you

The FOrmat function will be able to do this for you. (See the E-Basic help documentation for a complete description with examples)

score = Format$(percent/10,"0.0")

or

score = Format$(percent/10,"0.00")

for two decimals.
