php - Power big float numbers (100.33^360) -

i have problem:

pow(100.33, 360); // return inf 

i use gmp, not float number:

gmp_strval(gmp_pow('2', 3)); //return 8 gmp_strval(gmp_pow('2.0', 3)); //return 0 

please :) how it?

from php gmp documentation page:

these functions allow work arbitrary-length integers using gnu mp library.

in other words, no floating point allowed. gmp can floating point appears php interface doesn't use full power.

you can use bcpow functionality like:

$num = bcpow('100.33', '360', 20); echo $num; 

and outputs:
