+release builds have no overflow wrap checking
+don't rely on this behavior
+
+explicitly use
+`wrapping_*` methods to do this
+	such as wrapping_add
+Return the None value if there is overflow with the checked_* methods
+Return the value and a boolean indicating whether there was overflow with the overflowing_* methods
+
+wtf is this:
+  Saturate at the value’s minimum or maximum values with saturating_* methods
+
+there are f32 and f64 floats. f64 is default cause they are about the same speed
