How to get the maximum and minimum price in the Infoblock?

Question

1C-Bitrix

Good afternoon.
You need to get the maximum and minimum price and a couple of similar parameters in a certain section of the infoblock.
So far I only have 2 options:

1. 2 раза GetList, с максимальной и минимальной сортировкой по полю достать 1 элемент.
2. собственный sql запрос

But I am more than sure that in Bitrix it can be implemented without such crutches.
Please tell me how to implement it

Answer 1

The first option on your list. Just set nTopCount=1

Answer 2

Make a getlist, ONCE, sorting by price right there, you will get an array, you drag the base price from it through explode and that's it !!)
the first element of the array will be the minimum salary, the last - the maximum salary))
