This article mainly introduces how to use VBS to accurately calculate the power of 2 to the 100th power, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.
Since Python can calculate the power of 2 to the 100th power, I will implement it in VBS. But this efficiency, it took 0.009013 seconds to calculate the 10000 power Python of 2, and 120.9805 seconds to VBS, which is not a level, so I won't say much.
Go directly to the code:

ReDim w (n + t + 1)

For I = 0 To UBound (w)
W (I) = "0"
Next
For I = 0 To t
Dim c: C = 0
Dim uv: uv = 0
For j = 0 To n
Uv = (w (iSj)-"0") + c + _

W (iConj) = CStr (uv Mod 10 + "0")
C = uv\ 10
Next
W (i+n+1) = CStr (uv\ 10 + "0")
Next
Z = Join (w, "")
Z = StrReverse (z)
Do While Left (zPower1) = "0"
Z = Mid (zpj2)
Loop
Multiple = z
End Function
