value |
The number to be converted to hexadecimal. |
Notes
If the value is not a whole number, the decimal value will be truncated.
You can specify binary, Hex, or octal numbers by preceding the number with the & symbol and the letter that indicates the number base. The letter b indicates binary, h indicates Hex, and o indicates octal.
VB Compatibility Note: VB rounds the value to the nearest whole number so the Hex function will probably be changed in a future release to do this as well.
Sample code
Below are examples of various numbers converted to Hex:
Var hexVersion As String
hexVersion = Hex(5) ' returns "5"
hexVersion = Hex(75) ' returns "4B"
hexVersion = Hex(256) ' returns "100"
It is often useful to keep the same number of digits to represent a hexadecimal number, e.g. 8 characters for a 32 bits hexadecimal number. You can achieve such a task with the following code:
Function Hex32(value As Int32) As String
Const prefix = "00000000" ' A 32-bits value is 8 digits long at max
Return Right(prefix + Hex(value), 8) ' We always return 8 characters
End Function
For an Int64 integer, you can adapt it as:
Function Hex32(value As Int64) As String
Const prefix="0000000000000000" ' A 64-bits value is 16 digits long at max
Return Right(prefix + Hex(value), 16) ' We always return 16 characters
End Function
