Now that I have the answer (16.800000000000001), How do I round it of to 16.80 ? I only need it to be to the closest 1/100.

TIA

Johan,

You could try:

percentage = (42 * 250)/100

This gives the answer 105.
    

And that sounds weird, doesn't it?  42 is smaller than 250, so I'd expect it
to be less than 100% of the value...  In fact, it is 

  
42.0/250
        
0.16800000000000001
  
(42.0/250)*100
        
16.800000000000001
  

I suspect the problem is due to the fact that Python does integer division by
default: 

  
42/250
        
0
  

So, how to make it generic?

  
a = 42
b = 250
a / b
        
0
  
float(a)/b
        
0.16800000000000001
  

One of the members has to be a floating point so that floating point division
is performed instead of integer division.


Be seeing you,
