Introduction

This is a Fortran library containing mathematical procedures.

Currently implemented are:

Procedure	Description
gcDenom	Returns the greatest common denominator of two integer numbers.
numDigits	Returns the number of digits in an integer number
quadDiscriminant	Calculates the discriminant of a quadratic equation of the form ax^2 + bx + c = 0.
quadSolve	Finds the real roots of a quadratic equation of the form ax^2 + bx + c = 0.
binaryGap	Computes the number of bits in the longest continuous streak of 0-bits (or alternatively 1-bits) that are surrounded by 1-bits (or alternatively 0-bits) in an integer number.

The library includes a simple driver/test program. It allows the user to test the operation of the procedures for possible errors.

Building the library

• Install FPM (Fortran Package Manager) and copy it into your $PATH as fpm.
• Clone the git repository.
• Execute the command fpm build inside the base directory of the repository.
• This library includes a simple test program. It can be easily executed with fpm test.

This library was compiled with GFortran and packaged with FPM.

Note

The results obtained from the procedures contained by this library are not guaranteed to be correct. Use at your own risk.
