OMD have frequently cited Kraftwerk as major influences on their work, but this track was inspired by a 1970s opera. "I'll let you into a secret," OMD vocalist Andy McCluskey
told Classic Pop Magazine
, "the main influence on 'Decimal' is nothing to do with Kraftwerk, nor is it anything to do with Orchestral Manoeuvres In The Dark, and I cannot believe that no one actually spotted where 'Decimal' comes from. 1975, before Kraftwerk released the Radioactivity
album, and before we'd ever released anything: Einstein On The Beach
by Philip Glass. That's the most obvious reference."
