👉 The decimal point is a crucial symbol in mathematics that separates the whole number part from the fractional part of a number, enabling us to express values with precision beyond just whole numbers. It acts as a separator, indicating where the decimal portion begins, allowing for the representation of fractions and decimals. For instance, in 300.45, the decimal point divides the number into 300 (the whole number) and 0.45 (the decimal part). This notation is essential for performing arithmetic operations involving fractional parts and for clearly communicating numerical values that have both integer and fractional components.
