HEX$

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.
  • number can be any INTEGER, LONG or _INTEGER64 value, positive or negative.
  • number can also be any SINGLE, DOUBLE or _FLOAT value, but only the integer part of the value is converted in that case. That is, from the value -123.45 the function would convert the -123 only.
• 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
