Comparisons

RockMoney provides several methods to compare monetary values. All comparison methods automatically handle the parsing of input values, so you can compare against numbers, strings, or other Money objects.

Available Methods

isLessThan($money)

Checks if the amount is less than the provided value.

$price = rockmoney(10);
$price->isLessThan(15); // returns true
$price->isLessThan("5"); // returns false

isLessThanOrEqual($money)

Checks if the amount is less than or equal to the provided value.

$price = rockmoney(10);
$price->isLessThanOrEqual(10); // returns true
$price->isLessThanOrEqual(5); // returns false

isEqual($money)

Checks if the amount is exactly equal to the provided value.

$price = rockmoney(10);
$price->isEqual(10); // returns true
$price->isEqual("10.00"); // returns true
$price->isEqual(15); // returns false

isGreaterThanOrEqual($money)

Checks if the amount is greater than or equal to the provided value.

$price = rockmoney(10);
$price->isGreaterThanOrEqual(10); // returns true
$price->isGreaterThanOrEqual(15); // returns false

isGreaterThan($money)

Checks if the amount is greater than the provided value.

$price = rockmoney(10);
$price->isGreaterThan(5); // returns true
$price->isGreaterThan(10); // returns false

Input Formats

All comparison methods accept various input formats:

• Numbers (integers or floats)
• Strings containing numbers (with or without decimal points)
• Other RockMoney Money objects

The input is automatically parsed using the same rules as the Money object creation.
