REVISIONS and CHANGES
- 06/12/2010 V1.0 Thomas Forbriger
- 14/01/2011 V1.1 extended modifications:
- resolved problem with coordinate values close to zero which lead to a logarithm approaching infinity upon testing the number of significant digits
- resolved a problem with unreasonable large scale values in case of small round off errors in floating point coordinate values
- apply proper rounding to coordinate values, such that 0.0999999 will be stored as 0.1
- check actual round-off error rather than scale and issue a warning in cases where round-off error exceed 0.1%
- 29/03/2011 V1.2 - search for the smallest possible power larger or equal a desired value
- 22/01/2012 V1.3
- handle control parameters- pass control parameters to Coordinates and ScalCoo
- add conversion functions
- 24/01/2012 V1.4
- static cast of value to type float in function ScalCoo::set(const double&) caused terrible roundoff resulting in awfully many trailing digits. I see no reason for this cast and remove it.- reworked ScalCoo::smallestpower(const short&)
- 26/01/2012 V1.5 bug fix: ScalCoo::set(const double&): initial scale value must equal one see ticket:168
- 08/07/2016 V1.6 make correct use of new DATRW_report_assert
- 01/12/2016 V1.7 provide improved error message and warning to user
