Return value

A Boolean.

Exceptions

Examples

As stated earlier, all passed values must be of the same type and value and must be in the same order. Some of the following examples illustrate what happens when they are not.

let cssMathSum = new CSSMathSum(CSS.px(1), CSS.px(2));
let matchingCssMathSum = new CSSMathSum(CSS.px(1), CSS.px(2));
// Prints true
console.log(cssMathSum.equals(matchingCssMathSum));

let otherCssMathSum = CSSMathSum(CSS.px(2), CSS.px(1));
// Prints false
console.log(cssMathSum.equals(otherCssMathSum));

// Also prints false
console.log(CSS.cm("1").equal(CSS.in("0.393701")));
