 /**
- * Reimplements _Original_FloatMath with the standard libraries.
- * 
- * Math routines similar to those found in {@link java.lang.Math}. Performs
- * computations on {@code float} values directly without incurring the overhead
- * of conversions to and from {@code double}.
+ * Delegate implementing the native methods of android.util.FloatMath
+ *
+ * Through the layoutlib_create tool, the original native methods of FloatMath have been replaced
+ * by calls to methods of the same name in this delegate class.
+ *
+ * Because it's a stateless class to start with, there's no need to keep a {@link DelegateManager}
+ * around to map int to instance of the delegate.
  *
- * <p>On one platform, {@code FloatMath.sqrt(100)} executes in one third of the
- * time required by {@code java.lang.Math.sqrt(100)}.</p>
