Monks, would you know if there is a way to convert large numbers to strings without rounding or changes to the digits in the number?

I am trying to match phone numbers for repeating numbers like 99999999999999999999999999 using a simple pattern like /^(\d)(\1)+$/

However I run into truncation issues when the numbers get this large. If I have the number already as a string it is not a problem, however this is not always the case.

I tried the sprintf("%f",$num) but that add decimal places and rounding to the number which does not work.

Best Regards

Ty
