The HEX$ function returns the base 16 hexadecimal representation of an INTEGER, LONG or _INTEGER64 value as a STRING.


Syntax

result$ = HEX$(decimalNumber)


Description

  • The function returns the string hexadecimal (base-16) representation of decimalNumber.
  • The function does not return a leading sign space so LTRIM$ is not necessary.
  • VAL can convert the string value back to a decimal value by prefixing the string return with "&H": dec = VAL("&H" + hexvar$).


Examples

Example 1: Comparing decimal, hexadecimal and octal string values 0 to 15.

  
LOCATE 2, 20: PRINT "   Decimal | Hexadecimal | Octal  "
LOCATE 3, 20: PRINT "-----------+-------------+--------"
        template$ = "    \ \    |     \\      |    \\  "

FOR n% = 0 TO 15
  LOCATE 4 + n%, 20: PRINT USING template$; STR$(n%); HEX$(n%); OCT$(n%)
NEXT n%  
                     Decimal | Hexadecimal | Octal
                  -----------+-------------+--------
                       0     |     0       |    0   
                       1     |     1       |    1
                       2     |     2       |    2
                       3     |     3       |    3
                       4     |     4       |    4
                       5     |     5       |    5
                       6     |     6       |    6
                       7     |     7       |    7
                       8     |     8       |    10
                       9     |     9       |    11
                       10    |     A       |    12
                       11    |     B       |    13
                       12    |     C       |    14
                       13    |     D       |    15
                       14    |     E       |    16
                       15    |     F       |    17

Note: Decimal STR$ values contain a leading sign space so values require an extra space in the template using the slash format.


Example 2: Converting hex value to decimal.

h$ = HEX$(255)
PRINT "Hex: "; h$
PRINT "Converting Hex value to Decimal:"; VAL("&H" + h$)
Hex: FF
Converting Hex value to Decimal: 255
