we are self including here?

+#include "cc/math/int_point.h"

I guess unused in this header file.

private sections after public

the other we usually follow is:
public:
protected:
private:

+  template<typename FromType, typename ToType>
+  static ToType ClampFromTo(FromType value) {
+    ToType min = std::numeric_limits<ToType>::min();
+    ToType max = std::numeric_limits<ToType>::max();
+    if (value >= static_cast<FromType>(max))
+      return max;
+    if (value <= static_cast<FromType>(min))
+      return min;
+    return value;
+  }
+
+public:
+  static int ToInteger(double d) { return ClampFromTo<double, int>(d); }
+  static int ToInteger(float f) { return ClampFromTo<float, int>(f); }
+};
