New Comment:
This is an issue w/ the bcmath library itself, not a PHP bug. If you look in
ext/bcmath/libbcmath/src/raise.c
you'll see that in the function bc_raise(), the exponent is coherced to a long, and
the comments says:
/* Raise NUM1 to the NUM2 power. The result is placed in RESULT.
Maximum exponent is LONG_MAX. If a NUM2 is not an integer,
only the integer part is used. */
Suggest submitting as a bug to the author of bcmath (if you think it is a bug):

Unix/Linux command bc

Function bcpow is supposed to work with arbitrary precision
numbers. However, it seems to treat its second argument
as an integer.
E.g.
echo bcpow(256,0.5);
echo bcpow(256,0.99);
both produce 1. It seems that the second argument is
truncated down to integer value. Either this is a
feature and documentation must be changed or it is
a bug of either Windows version or even other versions
of BCMath/PHP.
bcpow(0.5,2); produces 0.25, which is all right.
