 				To detect whether the current build is 64-bit, or the type of architecture, don't use the architecture name. Instead, use [method OS.has_feature] to check for the [code]"64"[/code] feature tag, or tags such as [code]"x86"[/code] or [code]"arm"[/code]. See the [url=$DOCS_URL/tutorials/export/feature_tags.html]Feature Tags[/url] documentation for more details.
 				[b]Note:[/b] This method does [i]not[/i] return the name of the system's CPU architecture (like [method OS.get_processor_name]). For example, when running an [code]x86_32[/code] Godot binary on an [code]x86_64[/code] system, the returned value will still be [code]"x86_32"[/code].
