A decimal is a number that consists of two parts i.e. a whole number and a fractional part that is written with the help of separators such as a dot (.) that is called a decimal point. Let us learn more decimal notations, the definitions, and solve a few examples to understand the concept better.
A decimal is a number that consists of a whole and a fractional part. Decimal numbers lie between integers and represent numerical value for quantities that are whole plus some part of a whole. For example, in the given image, we have one whole pizza and a half of another pizza. This can be represented in two ways:
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form, since to do so would require writing out an inconveniently long string of digits.
Decimals are numbers with a fractional part, which is written after a decimal mark. The mark separates any whole part from the fractional part. Some examples of a decimal numbers are: 10.2, 0.23, and 19.999.
You can define the standard form of a whole number as follows. Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. For example, take the number 123,000,000; an easier way of writing this number is . 1.23 × 108;
Decimals are a numerical representation that enables us to express numbers with both whole and fractional parts. They are a fundamental concept in mathematics and play a crucial role in various applications, from everyday calculations to complex scientific and financial analysis.
