# Pi function from the decimal.py documentation
#
# NOTE: This is the pi function from the decimal documentation, modified
# for benchmarking purposes. Since floats do not have a context, the higher
# intermediate precision from the original is NOT used, so the modified
# algorithm only gives an approximation to the correctly rounded result.
# For serious use, refer to the documentation or the appropriate literature.
