What is the PineScript equivalent of MQL4's _Point? - mql4

Question

I am trying to convert this indicator to PineScript. Couldn't figure out how to get Point variable. Is there any way to achieve the same thing in PineScript?
_Point official definition:
The _Point variable contains the point size of the current symbol in the quote currency.
