As @Werner Stinckens​ said, it would be ok. But generally decimal column joins are not recommended as other factors come into play like the precision, length etc...Also when you are joining in on decimal columns, be sure to check out the abs value of...

sdf = psdf.to_spark().filter("id > 5")
sdf.show()
