HEX

Syntax HEX (hex$)
Location Toolkit II, THOR XVI

This function returns the decimal value of a hexadecimal number. The hexadecimal system of numbering is based upon base 16, which means that instead of each digit being in the range 0..9 (as in decimal), each digit can actually hold the value 0..15.

Because a digit can only be one character, a system was devised for representing the value 10..15 - these values are represented by the letters A..F respectively. Any digits outside the range 0..F will cause an ‘error in expression’.

Hex$ can be anything in the range $80000000 (which equates to -2^31) to $79999999 (which equates to 2^31-1).

Examples

PRINT HEX('F')

will print the value 15.

PRINT HEX('10')

will print the value 16.

CROSS-REFERENCE

HEX$ works the other way around, converting decimal numbers into their hexadecimal equivalent. See BIN and BIN$ for the binary versions. SMS users can achieve the same thing by using, for example:

PRINT $1AB

instead of:

PRINT HEX ('1AB').
