The result is not bizarre it is absolutely correct. The only difference
is that it is written in scientific notation.

http://en.wikipedia.org/wiki/Scientific_notation

I don't know why one PHP version switches to scientific notation earlier
than the other, but that might have something to do with the precision
setting in php.ini.

; The number of significant digits displayed in floating point numbers.
precision = 14

Check whether precision is set to the same value on both servers.

Bye!
