This function returns the hexadecimal (base 16) representation of any numeric value.
Syntax
- hexvalue$ = HEX$(number)
Description
- The function returns the base 16 (hexadecimal) representation of the given number as STRING.
- Different from STR$, this function does not return a leading sign placeholder space, so no LTRIM$ to strip that space from positive numbers is necessary.
- VAL can convert the returned hex string value back to a decimal value by prefixing the string with "&H".
- Eg. decimal = VAL("&H" + hexvalue$).
Examples
Example 1: Comparing decimal, hexadecimal, octal and binary string values from 0 to 15.
tabletop$ = " Decimal | Hexadecimal | Octal | Binary " tablesep$ = "---------+-------------+-------+--------" tableout$ = " \ \ | \\ | \\ | \ \ " 'the PRINT USING template LOCATE 2, 10: PRINT tabletop$ LOCATE 3, 10: PRINT tablesep$ FOR n% = 0 TO 15 LOCATE 4 + n%, 10: PRINT USING tableout$; STR$(n%); HEX$(n%); OCT$(n%); _BIN$(n%) NEXT n% |
- Note: Decimal STR$ values contain a leading sign placeholder space so values require an extra space in the tableout$ template using the slash format.
Decimal | Hexadecimal | Octal | Binary
---------+-------------+-------+--------
0 | 0 | 0 | 0
1 | 1 | 1 | 1
2 | 2 | 2 | 10
3 | 3 | 3 | 11
4 | 4 | 4 | 100
5 | 5 | 5 | 101
6 | 6 | 6 | 110
7 | 7 | 7 | 111
8 | 8 | 10 | 1000
9 | 9 | 11 | 1001
10 | A | 12 | 1010
11 | B | 13 | 1011
12 | C | 14 | 1100
13 | D | 15 | 1101
14 | E | 16 | 1110
15 | F | 17 | 1111
|
Example 2: Converting a hexadecimal value to decimal.
hexvalue$ = HEX$(255) PRINT "Hex: "; hexvalue$ PRINT "Converting Hex value to Decimal:"; VAL("&H" + hexvalue$) |
Hex: FF Converting Hex value to Decimal: 255 |
