Calculator precision is only 4 or 5 decimal places

[Steve Mottram]

The calculator application eOS appears to only operate to a very small number of decimal places precision, but allows much longer inputs to be provided, which are silently rounded. I would expect the application to offer the same precision as a typical physical desktop calculator, typically 8 or 10 decimal places. Testing suggests that the application is only working to around 4 or 5 decimal places.

Test 1: Enter "3.141592654*3.141592654" and press "=" Gives the result 9.8696, rather than the expected 9.869604404 from a desktop calculator.

Test 2: Enter the pi symbol and then "=". Gives the result 3.14159 rather than 8 or 10 digits of precision,
