Summation of Floating-Point Numbers in Cython
Adding up a list of floating point numbers: S n = \sum {i=0}^{n 1} x i seems simple. IEEE 754 double precision floats ( float64 ) carry about 15 to 17 significant decimal digits,…
Fully Amortized Loan simulation with Numba and IPyWidgets
In this blog post, we will show how to use Python to simulate the amortization of a fully amortized loan, such as a mortgage or a car loan. We will derive the formula for…

Running time of Dijkstra's algorithm on DIMACS networks with various implementations in Python . This post is the last part of a three part series: first part second part In the…
Dijkstra's algorithm in Cython, part 1/3
In this post, we are going to present an implementation of Dijkstra's algorithm in Cython. Dijkstra's algorithm is a shortest path algorithm. It was conceived by Edsger W.…
Dijkstra's algorithm in Cython, part 2/3
This post is the second part of a three part series. In the first part, we looked at the Cython implementation of Dijkstra's algorithm. In the current post, we are going to…
A Cython implementation of a priority queue
Credit: Musée de l'illusion, Lyon [picture taken by myself] In this post, we describe a basic Cython implementation of a priority queue . A priority queue is an important data…
Forward and reverse stars in Cython
This notebook is the following of a previous one, where we looked at the forward and reverse star representations of a sparse directed graph in pure Python: Forward and reverse…
