Details

Math methods are divided by categories: Common, Date, Text, Number, Financial. The Common math methods are available by default.
To enable math methods in the UI, you need to use the methods parameter and specify the category. The methods parameter can be set as a string, e.g.: methods: "financial" or as an array, e.g.:
methods:["number", "text"].
To switch on all the categories, use methods: "all". If the methods parameter is not specified, only the Common math methods are added to SpreadSheet.
