How do we convert exponent format into actual number from PHP

Question

How do we convert 8.64E+14 into actual value from PHP?

Answer 1

Cast to a float if not already a float, and printf() the result:

printf('%.0f', (float) '8.64E+14');

Note that casting to int won't work because that cast does not understand numbers expressed as strings in scientific notation. And on some systems, your given number is too large to fit into an int so PHP may make it a float instead.

Answer 2

It's already an actual value. The value type is float.

$float = 8.64E+14;
var_dump($float); //will give you float 8.64E+14
