The ariary is the currency of Madagascar. It is subdivided into 5 iraimbilanja and is one of only two non-decimal currencies currently circulating (the other is the Mauritanian ouguiya). Iraimbilanja means literally "one iron weight" and was the name of an old coin worth ​1⁄5 of an ariary.

1 arairy = 5 iraimbilanja. Jest to jedna z niewielu jednostek zdawkowych o tak specyficznej liczbie.
