roundDownTo: aNumber
	"Answer the next multiple of aNumber toward negative infinity that is nearest the receiver. 
	Examples:
               3.1479 roundDownTo: 0.01 -> 3.14
               3.1479 roundDownTo: 0.1 -> 3.1
               1923 roundDownTo: 10 -> 1920
               3.1479 roundDownTo: 0.005 -> 3.145
               -3.1479 roundDownTo: 0.01 -> -3.15"
	
	^(self / aNumber) 

Today I was doing a lot of changes on some variables in a deep hierarchy.

Current Pharo tools allow developers to find accesses to a variable in a class but not in a hierarchy so I had to make this snippet:

origin := AbstractWidgetPresenter.
variableName := #borderColor.
(origin slots detect: [ :e | e name = variableName ]) usingMethods collect: #methodClass as: Set
