A PROFESSOR from the Pamantasan Lungsod ng Maynila was recognized by the American Journal of Mathematics for his research on the Pi formula.

Prof. Roel Calano’s formula is a computer program and simulation that converges readily even after many iterations.

He devised an outstanding Pi formula that combines infinite summation and product, according to the university.

“The model and method can be used to test the speed, accuracy, and repagination process of Microsoft Excel. In addition, the formula can be utilized for digital signature, security, and numeric coding,” it said.

Calano is an alumnus and faculty member of the PLM College of Engineering.

American Journal of Mathematics is the oldest mathematics journal in continuous publication in the Western Hemisphere and ranks as one of the most respected and celebrated journals in its field.

Published in 1878, the Journal has earned its reputation by presenting pioneering mathematical papers.

It does not specialize but instead publishes articles of broad appeal covering the major areas of contemporary mathematics.

The Journal is used as a basic reference work in academic libraries, both in the United States and abroad.
