Houdini Round Decimal Size, Position and Rotation Geometries

Hello. I need help. I need to round geometry size, position and rotation values.

Before:

Example of 3D geometry with non-rounded size:
X 200,134 cm
Y 200,321 cm
Z 200,432 cm

After:

Example of 3D geometry with rounded size:
X 200 cm
Y 200cm
Z 200 cm

or

x 200.1cm
Y 200.3 cm
Z 200.4cm


I need to round the size by controlling the number of decimals, using VEX or Python in Houdini.
When exporting in FBX, USD or ABC, 3D geometry in CAD/3D software appears with rounded size, position and rotation.

The script should work for all geometries of various sizes, position and rotation. Not just the example.

in VEX rint(value) rounds value to closest whole number, to get decimals, use multiplications and divisions


rint(0.5215) -> 1
rint(0.5215 * 10) / 10 -> 0.5
rint(0.5215 * 100) / 100 -> 0.52
rint(0.5215 * 1000) / 1000 -> 0.522
