👉 Semincunum is a mathematical concept in number theory, particularly in relation to the representation of integers. It is used by mathematicians and computer scientists for representing large numbers that are too large to be represented as decimal or binary numbers with their usual precision limitations. A semincunum is an integer that can be written as a sum of powers of two. For example, 200 can be expressed as the sum of 100 + 1000 = 1
