Description Juro 2015-05-13 07:22:41 UTC
After upgrading Xamarin.Android to 5.1, we started to experience the wrong results when comparing the negative decimal values. It seems that it ignores the negative sign.
E.g. (decimal)0 < (decimal)-1 is true or (decimal)-2 > (decimal)1 is true

It only happens on Lollipop devices (Nexus 7 with Android 5.1 and LG G3 with Android 5.0). It works well on KitKat.

Our build has armeabi, armeabi-v7a and x86 (it has no 64bit support). The Target API level is 21 (Android 5.0). Minimum API level is 10 (Android 2.3.3).

It happens with both Mac and Windows version of the Xamarin tools.
