do not show number of bits

[komame]

Your issue is caused by changing the default value of 'Bits' on the first page of the Home Settings (the edit field next to the 'Integers' drop-down). By default, this value is set to 32, and since RGB also returns a 32-bit value, there's no need to specify that the given value has a different bit-width. However, if you changed the value to something other than 32, the system will indicate that the resulting value has a different bit-width by appending information about the number of bits used. When you change this setting back to 32, the RGB result will no longer have the ":32h" at the end.

In a program, you can control this setting using the Bits variable. For example, at the beginning of your program, you can set Bits := 32 so that regardless of what is set in Home Settings, running this program will always set 32. This is a global variable that causes a permanent change to the system settings, so it might be worth temporarily saving its value and restoring it to its previous state before returning the string after the conversion.
