Math.IEEEremainder isn't implemented and is commented as such at: https://github.com/google/j2cl/blob/master/jre/java/java/lang/Math.java#L34

Describe the solution you'd like

Add support for Math.IEEEremainder

Describe alternatives you've considered

I attempted an implementation based on this doc:

	static private double IEEEremainder(double dividend, double divisor) {
		return dividend - (divisor * Math.round(dividend / divisor));
	}

Additional context

The link above shows expected output, and there are tests for the Kotlin implementation.
