what is decimal
relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
for example: 1.2, 3.14, 12.567
Decimal is a base-10 numeral system, which means it uses ten symbols or digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent numbers. It is the most widely used numerical system in everyday life and is used to represent numbers like whole numbers, fractions, and decimal fractions.
In the decimal system, each digit's position in a number determines its value. The rightmost position represents ones, the next position to the left represents tens, the next represents hundreds, and so on. For example, in the decimal number 123, the digit 3 is in the ones position, the digit 2 is in the tens position, and the digit 1 is in the hundreds position.
To convert a number to decimal, you simply need to know the value of each digit in relation to its position. For example, the number 352 in decimal represents 3 hundreds, 5 tens, and 2 ones.
Decimal is used in various fields, including mathematics, finance, and everyday calculations. Many calculations involving money, quantities, measurements, and data are performed using decimals.
