Concept
Precision Format
Values in the EcoStruxure Building Operation software are stored in the EcoStruxure Building Operation database with all input decimals. If a stored value consists of more decimals than the operating system is defined to display, the value is rounded off according to the operating system settings before it is displayed in WorkStation.
For example, you enter the length 6.5282 m (21.4179 ft) to a variable in Building Operation. When you press Enter or OK, the value changes to 6.53 m (21.41 ft). This because of your operating system, in this example, is defined to display only two decimals. The input value 6.5282 m (21.4179 ft) is stored in the Building Operation database but is round off to 6.53 m (21.41 ft) when it is displayed.
The rounded value is only a display value and is not used by Building Operation in calculations or other operations.
If an integer value exceeds 12 digits (10 12 ), both positive and negative numbers, WorkStation displays the value in scientific notation. The number of digits for a decimal number before it is displayed in scientific notation is decided by the regional settings of the operating system settings where WorkStation is installed.
Sometimes the number of decimals on the same value differs depending on where the value is displayed. The reason for this is that the EBO server and WorkStation handles values in a different way.
The EBO server handles both float and double numbers. WorkStation only handles double numbers. So, when a float to double rounding is made sometimes extra decimals are added.
For example, the float value 0.2 that is saved to the EBO server the value might be presented as 0.200000002980232 the next time it is edited in WorkStation.
