With four digits, it’s 0.001.

What we need is a significand of 1 , because that’s the smallest one after 0 ..

## Is Infinity possible?

## Why is the sideways 8 the symbol for infinity?

## What is value of infinity?

INFINITY (∞) … When we say in calculus that something is “infinite,” we simply mean that there is no limit to its values. Let f(x), for example, be. . Then as the values of x become smaller and smaller, the values of f(x) become larger and larger.

What’s after trillion? Trillion is a 1 with 12 zeros after it, and it looks like this: 1,000,000,000,000. The next named number after trillion is quadrillion, which is a 1 with 15 zeros after it: 1,000,000,000,000,000.

## Is infinity minus 1 still infinity?

Infinity is uncountable. It is not defined. When there is no particular numerical value for infinity, this operation of infinity minus one can’t really be performed as it is illogical. So the answer still remains infinity.

## What is the highest number?

A googol is a 1 with a hundred zeroes behind it. We can write a googol using exponents by saying a googol is 10^100. The biggest named number that we know is googolplex, ten to the googol power, or (10)^(10^100). That’s written as a one followed by googol zeroes.
