I am working with some logical problems in my localhost. At a case I need to calculate power of 2 and sum them in integer type to proceed next case. I am using 32 bit system, so I can calculate up to 2^31, as well as sum up to 2147483648 in integer type.
How can I increase the number of power up to 10000? Is there any math library or class available to calculate big integer effectively?
Probably I dont need the power over thousand but I am curious if it is possible in PHP or not. Can anyone answer my with proper reference ?
There are two libraries available in PHP to work with BIG Numbers.
They are,
In both of them GMP has more library function then BC Math.
GMP - It considers leading zeros in a number string as meaning the number is in octal, whereas 'BC' doesn't. Reference: http://www.php.net/manual/en/book.gmp.php
