# What is mantissa? Explain with an example.

Decimals are a set of numbers written together with a dot in between them that is called a decimal point.

## Answer: Mantissa is the part of a number located after a decimal point.

Let's write Mantissa in terms of Decimal number

**Explanation:**

In a decimal number, Mantissa is the part of a number located after a decimal point.

Let's take a number 6.745

The mantissa is the part after the decimal point i.e, 0.745

### Mantissa in terms of Scientific Notation:

A regular number contains two significant components when written in Scientific notation

a) mantissa, and

b) exponent.

The exponent is always the number of times the mantissa pattern needs to be multiplied by 10 to obtain a value equal to the "regular number".

For example, the regular number 5367 in Scientific notation is represented as

5.367 × 10^{3}

The mantissa is 5.367 here.
