[Bug]: Rounding errors when printing floats/doubles

[andreasbaumann]

Describe the issue

On IA-32 floating point literals are internally different, so a simple string compare with Print is not portable:

~/googletest/googletest/test/googletest-printers-test.cc:464: Failure
Expected equality of these values:
  "1.1"
  Print(1.10000002f)
    Which is: "1.10000002"

~/googletest/googletest/test/googletest-printers-test.cc:466: Failure
Expected equality of these values:
  "9e+09"
  Print(9e9f)
    Which is: "8.99999949e+09"

[  FAILED  ] PrintBuiltInTypeTest.FloatingPoints (0 ms)

Expected equality of these values:
  "(1.1)"
  PrintToString(internal::Optional<double>{1.1})
    Which is: "(1.1000000000000001)"

[  FAILED  ] PrintOptionalTest.Basic (0 ms)

hey, I'd like to work on this issue

I'd be more than happy to take over the issue if someone can do a basic code walkthrough for me, regarding what all places do I need to look into and such.
