## Decimal Calculator

A decimal calculator is a tool used for performing mathematical operations on decimal numbers, which are numbers expressed in the base-10 numbering system.

## What are Decimal Numbers?

Decimal numbers are a type of numerical value that is expressed in the **base-10** numbering system, which uses the digits **0 **through **9 **to represent numbers. The value of each digit is determined by its position in the number, with the leftmost digit representing the largest value and the rightmost digit representing the smallest value.

Decimal numbers are commonly used to represent `non-whole numbers`

, such as fractions or percentages, and are used in a wide range of applications, including mathematics, science, engineering, and finance.

They can be added, subtracted, multiplied, and divided using basic arithmetic operations, and can also be used in more advanced mathematical operations like exponentiation, logarithms, and trigonometry.

## Examples

Some mathematical examples of using decimal numbers:

**Addition**: `3.5 + 2.8 = 6.3`

**Subtraction**: `7.9 - 4.6 = 3.3`

**Multiplication**: `1.2 x 5.3 = 6.36`

**Division**: `8.4 / 2 = 4.2`

**Exponentiation**: 2.5 raised to the power of 3 = 15.625

**Logarithms: **the logarithm of **100 **to base **10 **is **2**

**Trigonometry: **the sine of **30 **degrees is **0.5**

Decimal numbers are used in basic arithmetic operations like addition, subtraction, multiplication, and division, as well as in more advanced mathematical operations like exponentiation, logarithms, and trigonometry.

They are also used in a wide range of mathematical applications, including algebra, geometry, calculus, and statistics.
