Attribute Details
public Float
  accuracy
Notes: The accuracy of the data (e.g., the FunctionFlowports input or output).<br /><br />Example: An accuracy of 0.5 of the temperature means a communicated value of 19 represents an actual temperature of 19 +/- 0.5 degrees.
public Float
  resolution
Notes: The resolution of the data expressed as the size of the minimum difference between data values. <br /><br />Example: A resolution of 0.1 means that temperature may be represented in increments of 0.1 degrees.
public int
  significantDigits
Range:0 to 1
Notes: The number of significant digits, e.g., for the speed case: if the speed is a one digit number (e.g., 5 km/h), then this digit is significant, if the speed is a two digits number (e.g., 15 km/h), then the first digit is significant (here: 1), if the speed is a three digits number (e.g., 215 km/h), then the first two digits are significant (here: 21). Significant means here, that the respective digits are reliable.
