DEC2HEX

[Francis Ang]

I am trying to convert Decimal to Hex and found the following codes in Excel
community website. The function works fine except that when I enter decimal
values such as 112 or 160 or 208 nothing happens; there is no hex value
returned. These are the only numbers that I noticed so far, there could be
more!

Any reason for this?

Any help would be greatly appreciated.

I did a further check and found out that if the decimal values are 112, 128,
144, 160, 176, 192, 208, 224 and 240 no hex values will be returned.

I did not go through the code that you have posted but you can use
this code:

Function DecToHex(ByVal x As Variant) As String

Dim y

x = CDec(x)
Do
y = (x / 16 - Int(x / 16)) * 16
If y < 10 Then
DecToHex = y & DecToHex
Else
DecToHex = Chr$(y + 55) & DecToHex
End If
x = Int(x / 16)
Loop While x
End Function

Thanks for the suggestion, Jim.

Initially, I did not know understand your reply. Then it dawned upon me how
to apply of your suggestion to solve my problem.

Thank you, Jim.
