# How to check if the number is a repeating decimal?

As said in the question, I need something that can give me a boolean value that is either true or false according to the number. For example 7,7777... or 4,123123123... would return true. And 5,5 would return false.

Convert decimal to string and then you can see if next or previous number is same then number is repeate.

if you know the two numbers that generate the fraction you can find out if it is repetative or not. this is probably even better than converting to String ..

Logic will be previous and next number. But you need to check 2 number group and then 3 number group
