Q
What is the "n or more times" repetition quantifier? How to use it?
How to write a regular expression using a repetition quantifier to capture the value of PI like: 3.1415926535897932384626433832795028841971 with a precision of at least 5 decimal digits?

The "n or more times" repetition quantifier allows us to repeat a pattern unit at least n or more times. The "n or more times" repetition quantifier '{n,}' and it needs be placed immediately after the pattern unit. For example:
\d{10,} # matches '6973738433' from 'World population: 6973738433'
The regular expression to capture the value of PI with a precision of at least 5 decimal digits::
3\.\d{5,}
3\. - matches '3.'
\d{5,} - repeats \d at least 5 times
