Installation

Install the package using composer: composer require dovab/big-number

Usage

Create an instance of BigNumber with the first value. The value can be an integer, float, or a really big number as a string.

After creating the instance you can manipulate the value using the provided functions:

• add - To add another value to it
• subtract - To subtract a value from it
• multiply - To multiply the value by the given value
• divide - To divide the value by the given value
• modulus - To get the modulus of the given value

For example:

$number = new BigNumber('4839276542939265829734291003');
$number->setScale(4)
    ->add(5)
    ->multiply(11.98)
    ->subtract(new BigNumber('19478320759'))
    ->divide('9894675903.83755');
    
echo $number;

The BigNumber instance also has methods to compare the value to another value:

• equals
• greaterThan
• greaterThanOrEquals
• lowerThan
• lowerThenOrEquals
