Infra Suite performs all coordinate computations using double precision. All numbers are stored internally using the long format specified by the IEEE floating point standard. However, all numbers are displayed differently depending on the context and precision. Displaying full precision numbers to users may render displaying information useless, as floating-point numbers have a finite precision of roughly 16 significant decimal digits.

Application enables following coordinate display precision customization (based on specified coordinate dimensionality):

• Precision XY - display precision of X and Y ordinates.
• Precision Z - display precision of Z ordinate.

Please note that display precision does not affect rounding numbers - values simply get truncated. For example:

XY precision set to "0.0000" and Z precision set to "0.000" (3D coordinate dimensionality):

Actual value    = 100.4534932878, 200.2233402, 34.9949998

Displayed value = 100.4534, 200.2233, 34.994

XY precision set to "0.00" and Z precision set to "0" (3D coordinate dimensionality):

Actual value    = 100.4534932878, 200.2233402, 34.9949998

Displayed value = 100.45, 200.22, 34

XY precision set to "0.0000" and Z precision set to "0.000" (2D coordinate dimensionality):

Actual value    = 100.4534932878, 200.2233402, 34.9949998

Displayed value = 100.4534, 200.2233
