How values are shown
The numeric display shows the value of the Value connection at the data source. The value shown depends on whether the Value connection value is a floating point or integer value.
TIP:
In 32-bit floating point values, 1 bit is used for the sign (if any), 8 bits for the exponent, and 23 bits for the significant. This allows no more than seven digits. In

, floating point values are rounded to six digits. Therefore, using a floating point data type and adding to it a value that exceeds the six significant digits will result in a loss of precision.Floating point value | Integer value |
|---|---|
Value rounded to fit the display based on the Number of digits and Decimal places properties: Example: If "Number of digits" = 6,
and Decimal places = 2,
1234.56 rounded to 1234.6. If "Number of digits" = 6,
Decimal places = 1,
123.456 rounded to 123.5. | If Decimal places property = 0, value shown as is. If Decimal places property is greater than 0, the integer value will be shown, followed by enough zeroes to equal the Decimal places property. Example: If Number of digits = 6
and Decimal places = 2
123 displays as 123.00 If Number of digits = 6
and Decimal places = 4
123 would also be shown as 123.00 |
