+// std::numeric_limits<...>::digits10 is NOT the precision we want, cause
 // digits10 is the maximum number of base10 digits that (float|double)
 // can hold without loss, whereas we want the opposite: the minimum
 // number of base10 digits required to describe any (float|double
 // value) without loss.
+// Let's put it in another way: digits10 matters when you want to go
+// from base10 to floating-point and back to base10 without loss.

 // g++ 4.0.2 defines for instance:
 // <float>::digits10 = 6 and <double>::digits10 = 15
