Would suggest you to search for other options...
But you can perform such calculations using VBA...
Sub Example()
Dim x As Double, y As Double, z As Double
x = 1E-19
y = 1E-20
Range("A2").NumberFormat = "0.00000000000000000000"
Range("A2").Value = Format(x + y, "0.00000000000000000000")
End Sub
Open the visual basic editor (Alt+F11) and insert a module in your
project then copy the above code to the module. Run it by pressing F5
from your keyboard.
Data types with limited range wouldn't allow you to perform such high
level calculations in Excel, It'll be good if you'd switched to other
applications according to your needs.
