Proper Round Functions [QuantNomad]

Round function in PineScript is very simple and allows you to round numbers only to the closest integer number. This is a bit irritating because I very often have to round numbers to some decimal places and not integer.
So I created 2 functions I use all the time and now sharing them with you.

• roundn - rounds the values in its first argument to the specified number of decimal places.
  
• roundtick - rounds the values to current symbol mintick
  

I hope they will be useful for you.
