**What number is 1e9?**. In this article we will let you know details of your question. Also we will share with most asked related question by peoples end of this article. Let's check it out!

## What number is 1e9?

-1e9 is **-1000000000.0** ; the minus sign applies to the number itself. The e (or E ) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”. In mathematical scientific notation, this is usually denoted by a superscript: 1 × 10-9 or -1 × 109.

## How do you read e in numbers?

On a calculator display, E (or e) stands **for exponent of 10**, and it’s always followed by another number, which is the value of the exponent. For example, a calculator would show the number 25 trillion as either 2.5E13 or 2.5e13.

## Is E the same as x10?

It means exponential, which means multiplied by 10 to the power of the number after the “e”. So in this case it means **2 * 10^10**.

## What is E in math log?

The number e, also known as Euler’s number, is a **mathematical constant approximately equal to 2.71828**, and can be characterized in many ways. It is the base of the natural logarithm. It is the limit of (1 + 1/n)n as n approaches infinity, an expression that arises in the study of compound interest.

### What does it mean E 01?

E+01 means **moving the decimal point one digit to the right**, E+00 means leaving the decimal point where it is, and E–01 means moving the decimal point one digit to the left.
