You could try

date( month ( myDate ) ; 1 ; year ( myDate ) )- 1

You use many variable but they all used only once, it can be written as
myDate - Day ( myDate )
//date - number is date, then don't need getasdate.

And the parameter myDate should be date type, then sample input is wrong. Something like
PreviousMonthEndDate( GetAsDate("01/03/2018"))

Tim, even shorter :

date( month ( myDate ) ; 0 ; year ( myDate ) )
