Say I want to multiply x variable by y but I want to make sure the value of x is less than 1.0

x=x*y
if x>1.0 then x=1.0

Is there any better or simple way to doit?
 
If you want to just limit the value after multiplying it, without rescaling / normalizing the values you could do this

Code:
x = Max(1.0,x)

EDIT
Sorry that should be Min not Max of course, so it outputs the smallest number of the two!

Thanks. that what i need.

about rescaling / normalizing. im intrested to know what is that and maybe some example usage.
 
Great. Sure I can show a few examples, two simple useful ones I can think off would be these:
Code:
Import mojo2

Function Main()
    New MyApp
End


Class MyApp Extends App

    Field canvas:Canvas
 
    Method OnCreate()
        canvas= New Canvas()
  
        ' Min-Max Normalization
        Local min :Float = 0.0
        Local max:Float = 50.0
        Local value:Float = 25 ' Value here
        Local a:Float, b:Float
        Local newmin:Float = -20.0
        Local newmax:Float = 20.0
 
        ' #1 Convert a range of values (min - max) into the range 0.0 - 1.0
        Local output:float = (value - min) / (max - min)
        Print output

        ' #2 Convert a value from ANY range to ANY other range, linearly
        a = (newmax - newmin) / (max - min) ;  b = newmax - a * max ; output = a * value + b
         Print output
    End
 
    Method OnUpdate()
 
    End
 
    Method OnRender()
        canvas.Clear
        canvas.Flush
    End
 
End
