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


Contents

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
