To-hex - Function Summary

Summary:

Converts an integer to a hex issue!.

Usage:

to-hex value

Arguments:

value - Value to be converted (must be: integer)

Description:

The TO-HEX function provides an easy way to convert an integer to a hexidecimal value.

print to-hex 123 0000007B

The value returned is a string of the ISSUE datatype (not the BINARY datatype). This allows you to convert hex values back to integers:

print to-integer #7B 123

Note: To convert HTML hex color values (like #80FF80) to REBOL color values, it is easier to do the conversion to binary and then use a base 16 encoding:

to-html-color: func [color [tuple!]] [ to-issue enbase/base to-binary color 16 ] print to-html-color 255.155.50 FF9B32

The TO-ISSUE function is just used to add the # to it.

To convert from an HTML color back to a REBOL color tuple, you can use this:

to-rebol-color: func [color [issue!]] [ to-tuple debase/base color 16 ] to-rebol-color #FF9B32

If the HTML color value is a string, convert it to an issue first. The function below will work for strings and issues:

to-rebol-color2: func [color [string! issue!]] [ if string? color [ if find/match color "#" [color: next color] color: to-issue color ] to-tuple debase/base color 16 ] to-rebol-color2 "#FF9B32"
