Android Question Doubt - Convert To Double and To String

[Fabvitor]

Doubt

I want to get numeric values, convert to double, perform operations and return to the textbox as string

How do I do?

Code:

Sub Button3_Click
Dim pa As Double, pb As Double, pc As Double, pda As Double, pdb As Double, pdc As Double, pd As Double, pcd As Double, pcc As Double
Try
pa = EditText1.Text
pb = EditText2.Text
pc = EditText3.Text
pda = EditText4.Text
pdb = EditText5.Text
pdc = EditText6.Text

pd = (pda * pa) + (pdb * pb) + (pdc * pc)
pcc = (pdc * pc)
pcd = (pdc * pc) / pd

pcc = EditText7.Text
pd = EditText8.Text
pcd = EditText9.Text
Catch
Log(LastException)
End Try
End Sub

Please use [code]code here...[/code] tags when posting code.

1. Strings are converted to numbers automatically.
2. Use NumberFormat to convert a number to string.
3. Use IsNumber to test whether a string can be parsed to a number.

pd = (pda * pa) + (pdb * pb) + (pdc * pc)
pcc = (pdc * pc)
pcd = (pdc * pc) / pd

pcc = EditText7.Text
pd = EditText8.Text
pcd = EditText9.Text

The last three lines look strange to me.
You are calculating pd, pcc and pcd.
I thinl that you want to show the results in the EditText views.
If yes the code must be:

EditText7.Text = NumberFormat(pcc, 1, 2)
EditText8.Text = NumberFormat(pd, 1, 2)
EditText9.Text = NumberFormat(pcd, 1, 2)

You can change the two values in NumberFormat to your needs.
