        }

        if (value >= 1) {
            return value.toFixed(2) +"";
        }

        if (value < 1 && value > 0) {
            return value.toPrecision(3);

        return value + "";
    }

Nice function, very useful.

I'd add the following:

const valueConditionCheck = Math.abs(value);

Then I can check the conditions with abs to also include the negative side with your custom format, but return the value with the correct format.

Best
