A finite number of digits refers to any numerical representation that has a limited count of digits, such as whole numbers, integers, or specific decimal numbers that terminate. For example, the number 1234 has four digits, while the decimal number 3.14 has three digits before the decimal point and two after it, making a total of five digits. In contrast, Irrational Numbers like π or repeating decimals like 1/3 have infinite digits.

Why is 3.14 rational but π is not?
3.14 has a finite number of digits. All numbers with a finite number of digits are rational. Pi has an infinite number of digits, AND the digits don't repeat in a regular pattern. (Numbers with repeating decimals are rational as well.)
Repeating decimal definition?
A repeating decimal is a number expressed in decimal form in which, after a finite number of miscellaneous digits, the number continues with a string of a finite number of digits which repeats itself without end.
What are decimals that have a finite number of digits?
Decimals that have a finite number of digits are known as terminating decimals. These numbers can be expressed as fractions where the denominator is a power of 10. For example, 0.75 and 0.5 are terminating decimals, as they can be written as 75/100 and 5/10, respectively. In contrast, non-terminating decimals, such as 0.333..., do not have a finite number of digits.
What are examples of finite and infinite sets?
Some finite numbers in a set: the number of digits on your hand, the number of seats on a bus, and the number of people on earth. Some infinite numbers in a set: the number of positive integers and the number of digits in pi.
Does pi represent a finite or infinite number?
Pi is an irrational number. As such, it has an infinite number of digits.
