`
`

*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:**

**Description:**

Returns the unsigned hexadecimal string representation of the integer

If you specify

The length of the string will not go longer than the maximum number of digits required for the type of

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

`. Hexadecimal digits range from 0-9, or A-F.`*number*If you specify

`> 0, the result string will be exactly that length. It will be truncated or padded with zeros on the left, if necessary.`*digits*The length of the string will not go longer than the maximum number of digits required for the type of

`(8 for a`*number*`long`, 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 to an integer type, using a function like`Cint`, similarly to a normal numeric string. E.g.`Cint("&HFF")`**Examples:**

'54321 is D431 in hex

Print Hex(54321)

Print Hex(54321, 2)

Print Hex(54321, 5)

Print Hex(54321)

Print Hex(54321, 2)

Print Hex(54321, 5)

will produce the output:

D431 31 0D431

**Dialect Differences:**

- The string type suffix "$" is required in the
*-lang qb*dialect. - The string type suffix "$" is optional in the
*-lang fblite*dialect. - The string type suffix "$" is ignored in the
*-lang fb*dialect, warn only with the*-w suffix*compile option (or*-w pedantic*compile option).

**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.
