Question :
What exactly is the Function of A Decimal Point ?

Answer :
A number system is not complete unless it may be used to express fractional parts of a unit by means of place values.
The decimal point identifies the one's place and therefore it serves as a separatrix between a unit and a part of a unit.
The decimal point is used to separate the integer part of a decimal number from its fractional part.
In the United States, the decimal point is usually aligned with the bottom of the digit, while in the United Kingdom it is usually centered. In Europe, a comma is used.
