+Efficient binary-decimal and decimal-binary conversion routines for 
+IEEE doubles. 
+
+The library consists of efficient conversion routines that have been 
+extracted from the V8 JavaScript engine. The code has been refactored 
+and improved so that it can be used more easily in other projects.
+
+There is extensive documentation in 
+  double-conversion/double-conversion.h
+
+Other examples can be found in 
+  test/cctest/test-conversions.cc

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
