Summary 0007134: Float rounded is inexact
Description try 5000000000000001.0 rounded -> 5000000000000002

Since 5000000000000001 highBit -> 53, this number is represented exactly
- you can check with 5000000000000001.0 asTrueFraction -> 5000000000000001 -
it should convert correctly to nearest integer.
Additional Information This is a minor thing but one step toward ISO/IEC 10967-2
