php variables help with a big number

Question

Hello i need to know if php there is a variable type that doesn't show me something like this:

3.9614081257132E+28

Please anyone knows how to make that?

Answer 1

Try printf() to print the variable:

echo sprintf("%f", 3.9614081257132E+28);
// prints 39614081257132001671004553216.00000

Or without the decimal digits:

echo sprintf("%.0f", 3.9614081257132E+28);
// prints 39614081257132001671004553216

If you need arbitrary precision numbers, try the bcmath and GMP modules.

What you get is just a standard way of displaying "long" real numbers.

Answer 3

There are no "big num" types in PHP. However, there really isn't anything to stop you from building a class that is capable of representing a big integer. You can do this with the string data type.
