Decimal Representation
Decimal representation refers to the way numbers are expressed using a decimal point to separate the whole number part from the fractional part. Each digit after the decimal point represents a fraction of ten, allowing for precise expression of values that are not whole numbers. This concept is crucial for writing and understanding numbers in various contexts.
