DECIMAL NUMBERS

__DECIMAL__

**The numbers which are written in Decimal form are called Decimal Numbers. The numbers which are
mentioned below are called Decimal numbers –**

**12.254, 7.024, 56.34,
48.375, 1257.23, 89.0008 are all decimal numbers**

**You would wish to
know that, every Decimal Number has two parts - **

**
1) Whole Number part**

**
2)
Decimal Number part **

**Both of these parts ****together**** make Decimal Numbers and these two parts are separated by a dot ‘.’
and this dot ‘.’ Is called Decimal Point.**

**In a decimal number
system, the 1) Whole Number part is to be placed on the left side of the Decimal Point
and 2) Decimal Number part is to be placed on the right side of the Decimal Point.**

**Absence of any of the
part 1) Whole Number or 2) Decimal Numbers is denoted or express by ‘0’ Zero.
For example, .234 can be written as 0.234 and 52 can be written as 52.0, the value of ‘0’ Zero just before or after the decimal Point are valueless but if the position of zero is between the decimal point and numeric digit then obviously the value of ‘0’ Zero is there, for example, 20.12, 47.05, 23.008 **
