Decnawazilion

Decnawazilion is a proposed name for the number in the Namkaran naming system for extremely large numbers. It is defined as 1 followed by one quadrillion zeros.

Mathematical definition

Decnawazilion is defined as:

This means that a decnawazilion is 1 followed by 1,000,000,000,000,000 zeros. It has 1,000,000,000,000,001 digits in total.

The name belongs to the proposed Namkaran framework, which describes a naming system for hyperlarge numbers.

Comparison with other large numbers

Namkaran framework

The Namkaran framework proposes names for numbers with extremely large values. It extends naming beyond familiar numbers such as a googol by introducing additional names for higher orders of magnitude.

Within this proposed system, decnawazilion follows novanawazilion and precedes quinawazilion.

These names are proposed terminology and are not standard mathematical terms in general use.
