It seems some frequently used macros on iOS are undefined in Elements.
The FLT_MIN/FLT_MAX/… are marked as errors “Unknown identifier” by Elements compiler, which are defined in “float.h” on iOS and can be referenced directly in XCode.
BTW:
I’ve found MIN/MAX/ABS macros are working well in Elements. And I can see RemObjects.Elements.System.__Global defines lots of functions mapping to these macros.
