This changes the behavior of builtin math to floating point by default. If the result of a computation is an integer, then it will be printed as an integer; otherwise it will be printed as a floating point decimal with up to 'scale' digits past the decimal point (default is 6, matching printf). Trailing zeros are trimmed. Values are rounded following printf semantics. Fixes #4478
