Irrational number or repeating decimal
A whole number??
Pi is in fact a never ending number since it's decimal part goes on for ever and has no specific pattern. Ha!
The decimal that never stops is called recurring decimal. For example - 1/3 = 0.3333... and goes on. Such decimals are written with a dot or bar on top of the numbers which are repeating.
yes, repeating decimals (those that have infinite - never ending - number of digits after the decimal point and these decimals show repeating pattern) are rational numbers, because they can be written as fractions.
