Decimal: meaning, definitions and examples
๐ข
decimal
[ หdษsษชmษl ]
mathematics concept
A decimal is a fraction expressed in a standard form, where the denominator is a power of ten. It allows for the representation of non-integer values and is often used in measurements, currency, and calculations. Decimals are typically written with a decimal point to separate the integer part from the fractional part. For example, 2.5 represents 2 and a half, while 0.75 represents three-quarters of a whole. The use of decimals simplifies arithmetic operations like addition, subtraction, multiplication, and division.
Synonyms
decimal fraction, fraction.
Examples of usage
- The price of the item is $5.99.
- You can express 0.5 as a decimal.
- In mathematics, 1.25 is a decimal representation of a rational number.
mathematics representation

Etymology
The term 'decimal' originated from the Latin word 'decimus', which means 'tenth'. The concept of decimal numbers has been utilized since ancient civilizations, particularly by the Babylonians and Egyptians. However, it was the Hindu-Arabic numeral system that fully developed the decimal system we use today. Introduced to Europe in the late 10th century, it revolutionized mathematics and commerce by providing a simpler way to calculate and represent numbers. The decimal system became widely adopted for its practical applications, leading to its current prominence in mathematics and various fields. Over time, the concept expanded to include decimals in both fractional and percentage forms, establishing its integral role in modern numerical representation.
