Why ~ sign used before number?

Question

I saw in many places that there some number is presenting with prefixing the ~ sign. Actually, I couldn't understand the reason why they use this special character before a number.

As an example- Every mobile PPI number is presenting with prefixing this special character ( ~403 ppi density ).

The tilde character (~) is often used before a number to indicate that it is an approximation.
