Android Question String numerals to number and back again

[Colin Evans]

I've searched but couldn't find the answer so please help

I have two labels containing a numeric value i.e. lblA.text = "2.14" lblB.text = "7.35" i want to be able to multiply them together and then put the resulting value in lblC.text = "‭15.73" , and round the result up to two decimal places, hope you can point me in the right direction

Never use Views to make calculations, use Variables.

Dim dblA, dblB, dblC As Double

dblA = lblA.Text
dblB = lblB.Text
dblC = dblA * dblB

lblC.Text = NumberFormat2(dblC, 1, 2, 2, True)
