e764bc50 - feat: round numbers to reduce undeterministic behavior (#3740)

feat: round numbers to reduce undeterministic behavior (#3740) This PR rounds the floating point number associated with coordinates in `pdfminer_processing.py`. This helps to eliminate machine precision caused randomness in bounding box overlap detection. Currently the rounding is set to the nearest machine precision for `np.float32` using `np.finfo(float)`, which yields resolution = `1e-15`. ## future work We should reduce the rounding to only 6 digits after floating point since the data type `float32` has a resolution of only `1e-6`. However it would break tests. A followup is required to tune the threshold values in `pdfminer_processing.py` so that it works with `1e-6` resolution.
