# Scientific notation calculator

## Result:

### 9e-28 = 9 × 10^{-28}

### 9e-28 = 9 * 10^-28

### 9e-28 = 9e-28

## Engineering notation:

### 9e-28 = 900 × 10^{-30}

### 9e-28 = 900 × 10^{-30}

### 9e-28 = 900e-30

Calculator for converting numbers to scientific notation - semilogarithmic shape

Weight The Sun is about 2*10

**m * 10**. m = mantissa, e = exponent, 10 = decadic base. The construction of a number allows calculations with very large but also very small real numbers (Physical calculations) with the efficient use of computer computing.^{e}Weight The Sun is about 2*10

^{33}grams, the weight of the electron is about 9*10^{-28}gram. We would need at least 202-bit numbers to calculate with both of these numbers in fixed-point arithmetic. However, we do not use such great accuracy either, because we know the two numbers with an accuracy of about five digits. Therefore, in scientific calculations we use floating point numbers, also called semilogarithmic shape or scientific notation
