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.
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.)
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.
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.
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.
Pi is an irrational number. As such, it has an infinite number of digits.

No. Any number which has a finite number of digits if RATIONAL.
If it has a finite number of decimal digits, it's rational.
No. Any number that has a finite number of digits is rational.

ANY number that has a finite number of digits is rational.
Any time a number has a finite number of digits, it is rational.
It was presumably proven when it was discovered that there were infinitely many counting numbers. However, whoever it was, did not consider the mathematical possibility with practicality. The universe has a finite life. Within that our solar system is finite. People, in their turn, have finite lives. In a finite life you can only "dial" a finite number of digits. therefore, you can only call a number if it has a finite number of digits. For any finite number of digits, there are only a finite amount of phone numbers. So, having infinitely many telephone numbers is no use if you need to wait an infinite amount of time (longer than you'll live) for the first person to call you!
