Ziffer
🔢 What exactly is a Ziffer?
Die Ziffer (plural: die Ziffern) refers to a single written character used to represent numbers. In the decimal system, these are the Arabic numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
It's important to distinguish die Ziffer from die Zahl (the number):
- A Ziffer is a symbol (e.g., '7').
- A Zahl is a value or quantity, often consisting of one or more Ziffern (e.g., '17', '3.14', '1024').
⚠️ Don't confuse die Ziffer (digit/figure) with die Zahl (number)! The number 42 (Die Zahl 42) consists of the digits 4 and 2 (den Ziffern 4 und 2).
