yac-math v3.1.5

yac-math

helper functions math library

basic usage

• npm install yac-math

available methods

returns Array

• getUniquePrimeFactorsList( value ) => returns a list of unique prime factors for the given input value
• getPrimeFactorsList( value ) => returns a list of prime factors for the given input value, their product is equal to the input value

returns boolean

• checkIsFactor(nb1, nb2) => checks if input nb1 is a factor of input nb2
• checkIsMultiple(nb1, nb2) => checks if input nb1 is a multiple of input nb2
• isEven( value )
• isNaturalNumber( value )
• isPrimeNumber( value )

returns Number

• getPercentageRepresentation(nb1, nb2) => gets what percentage of nb2 represents nb1

returns String

• getUnitRatioOfNb1ToNb2(nb1, nb2) => gets a string representation of the ratio of one unit of nb1 to nb2

importing and using

    // you can use the default export
    const yacMath = require( 'yac-math' );
    yacMath.isPrimeNumber( 5 ); // => true

    // OR you can pick the functions you want
    const {isEven, isNaturalNumber, isPrimeNumber} = require( 'yac-math' );
    isPrimeNumber( 5 ); // => true
    getPercentageRepresentation(2, 4); // => 50

tests

I use Jest and jest-theories for testing. You can run the tests with npm run test.
