+Summary:        Library providing binary-decimal and decimal-binary routines for IEEE doubles
+Name:           double-conversion
+Version:        3.1.5
+Release:        1
+License:        BSD
+URL:            https://github.com/google/double-conversion

+%description
+Provides binary-decimal and decimal-binary routines for IEEE doubles.
+The library consists of efficient conversion routines that have been
+extracted from the V8 JavaScript engine. The code has been re-factored
+and improved so that it can be used more easily in other projects.
