Requirements

• Python 3.7

This code makes use of the f"..." or f-string syntax. This syntax was introduced in Python 3.6.

Sample Execution & Output

If run without command line arguments, using

./precisionEstimate

the following usage message will be displayed.

Usage: ./estimatePrecision.py num_execs [arbitrary precision]

If run using

./precisionEstimate 1000000

output simliar to

           float|  3.7247|2.220446049250313e-16
 float-type-hint|  3.6731|2.220446049250313e-16
      Decimal-28| 31.8602|0.999999999999999999999999999

will be generated. Note that the float and float-type-hint lines may vary.

An optional precision command line argument can be supplied to change the arbitrary precision used by the Python decimal module. For example:

./precisionEstimate 1000000 16

will generate output similar to

           float| 0.3979|2.220446049250313e-16
 float-type-hint| 0.4053|2.220446049250313e-16
      Decimal-16| 3.1643|0.999999999999999
