Hex
Returns the hexadecimal of the given number
Syntax
`
Declare Function Hex Overload ( ByVal number As Byte ) As String
Declare Function Hex ( ByVal number As Short ) As String
Declare Function Hex ( ByVal number As Integer ) As String
Declare Function Hex ( ByVal number As Integer, ByVal digits As Integer ) As String
Declare Function Hex ( ByVal number As LongInt ) As String
Declare Function Hex ( ByVal number As LongInt, ByVal digits As Integer ) As String
`
Usage
`
result = Hex[$]( number [, digits ] )
`
Parameters
`number`
A number or expression evaluating to a number. A floating-point number will be converted to a `LongInt`.
`digits`
Optional number of digits to return.
Return Value
A String containing the unsigned hexadecimal representation of `number`.
Description
Returns the unsigned hexadecimal string representation of the integer `number`. Hexadecimal digits range from 0-9, or A-F.
If you specify `digits` > 0, the result string will be exactly that length. It will be truncated or padded with zeros on the left, if necessary.
The length of the string will not go longer than the maximum number of digits required for the type of `number` (8 for an `Integer`, 16 for a `LongInt)`.
If you want to do the opposite, i.e. convert a hexadecimal string back into a number, the easiest way to do it is to prepend the string with `"&H"`, and convert it using `ValInt` or `ValLng`, similarly to a normal numeric string. E.g. `ValInt("&HFF")`
Example
`
'54321 is D431 in hex
Print Hex(54321)
Print Hex(54321, 2)
Print Hex(54321, 5)
`
will produce the output:

    D431
    31
    0D431

Dialect Differences

- The string type suffix `"$"` is obligatory in the -lang qb dialect.
- The string type suffix `"$"` is optional in the -lang fblite and -lang fb dialects.

Differences from QB

- In QBASIC, there was no way to specify the number of digits returned.
- The size of the string returned was limited to 32 bits, or 8 hexadecimal digits.
