Description:
picompute 3.14.15926
this is toy tool to compute the N digits of pi
usage
install
python3 -m pip install pi-compute or
python3 -m pip install --index-url https://pypi.org/simple/ pi-compute
python usage
python3 -m pi_compute.pi 1000
import pi_compute as pi; pi.compute(1000)
cpp usage
make pi_thread for two threads
make pi_v2 for single thread
implementations
pi.d:this is the original d language implementations of pi
pi.cpp: motivated by pi.d and use two threads to build the dynamic shared library
test/pi_v2.cpp is single thread
test/pi_thread.cpp is two threads
