Yes and no. It's all about context.
When saying something like "one fifteen" (Eins Fünfzehn) it can be understood as 1.15 . Like in
Das macht dann eins fünfzehn (1.15€)
Zusammen ergibt das eine Summe von zwei fünfzig (2.50€)
(Please note: It's more likely you will hear something like Zwei Euro Fünfzig or Zwei Euro und Fünfzig Cent)
But, when talking casually about higher numbers like 2,500 one can say
Zwei Fünf (two five)
Für das Auto gebe ich dir keine drei (3,000€), sondern maximal zwei fünf (2,500€)
I would like to add @VolkerLandgraf's comment:
What [the answer] did not explicitly say is that the single separated digit would never be used or understood as a multiple of hundred - depending of context it would mean multiples of one or thousand (or occasionally millions)
He's right, but please note for millions++ it's more common to say "Eins Komma Fünf (1,5) Millionen" for 1.500.000 or "Zwei Komma Drei Vier (2,34) Millionen" for 2.340.000 . Like English's "one point five million".
