Rounding to 2 decimal places

Can someone help me with rounding this expression to 2 or 1 decimal place?

x = =y/(100-z)*100 y and z is variable

x = =3.2/(100-10)*100 will give 3.555555556 want 3.56
x = =20/(100-49)*100 will give 39.21568627 want 39.22

this will be passed onto a label.text

Hi this will help you I think

Use the format command same as in vb6

Here is the full example

Dim s as String
s=Format(39.21568627, “#.##”)
msgbox s
