Strings That Look Like Huge Floating Point Numbers

Browse Source 
Fix #4776. DefaultValueBinder treats strings that look like scientific notation as floats. However, if Php evaluates them as `INF`, this can cause problems for Excel. A one-line change to DefaultValueBinder avoids this situation. Tests are added for DefaultValueBinder, and also for StringValueBinder and AdvancedValueBinder, although those extend DefaultValueBinder and needed no code changes.
