Rounding a number for limited decimals

how can I write aevent procedure code to round a number to two decimals?
I am wrighting something similer to this
a=val(x)+val(Y)
I Know in exel "Round,2" Makes a number to Two Decimals.

Use the Math.Round method, e.g.

VB Code:

Dim myDouble As Double = 1.23456789
 
myDouble = Math.Round(myDouble, 2)
MessageBox.Show(myDouble.ToString()) 'Displays 1.23
 
myDouble = 9.87654321
 
myDouble = Math.Round(myDouble, 2)
MessageBox.Show(myDouble.ToString()) 'Displays 9.88
