Hex$ ( value )
Parameters
| value - the integer to convert |
Description
|
Converts an integer into a hexadecimal string. The result is always eight uppercase digits, zero padded, with no "0x" or "$" prefix: Hex( 255 ) is "000000FF" and Hex( -1 ) is "FFFFFFFF". Because the width is fixed you never need to pad it yourself for a debug display, and if you want it shorter, take the last few characters with Right. Hex earns its keep with colours and bit flags. A packed RGB value printed as hex is instantly readable against the values you typed into your art tool, and a flags word in hex shows you exactly which bits are set. It is also the friendliest way to dump a byte you read from a file or a bank while working out a format. There is no matching "unhex" command, but you can read a hex literal directly in source by prefixing it with a dollar sign, as in $FF00FF. See also: Bin, Str, Right, And. |
Example
; Hex Example ; ----------- ; Hex$ converts an integer to its hexadecimal (base 16) text form, ; always 8 digits - the same notation as $ literals in source code. Print "Hex$(10) = "+Hex$(10)+" (A is 10 in hex)" Print "Hex$(255) = "+Hex$(255) Print "Hex$(4096) = "+Hex$(4096) Print "Hex$(65535) = "+Hex$(65535) Print "Hex$(-1) = "+Hex$(-1)+" (all 32 bits set)" Print "" ; Hex is the natural way to read packed colour values: $RRGGBB orange=$FF8000 Print "The colour literal $FF8000 is "+orange+" in decimal" Print "Hex$ makes it readable again: "+Hex$(orange) Print "" Print "Press any key to close the example" WaitKey End
