Question

Can any one please let me know the Regex used to find numbers which is of multiples of 4 from a given string. The string will consist both text and numbers.

Thanks in advance

Answer 1

With regex you can only extract whole numbers. However it is possible to extract only even numbers:

(\d*[02468])

Then you have to check them if they are dividable with 4 with modulo test:

if ( ( number != 0 ) && ( number % 4 == 0 ) ) {
  // number is dividable with 4 and does not equal 0
}
