After reading all of the notes for this page, I suggest that any casual PHP coder beware. Please consult someone with an actual understanding of floating point issues before developing a serious application, such as one dealing with money in any form. Also, in the note I just posted, I suggested using integers for monetary values. PHP does not currently support 64 bit integers on platforms where int is normally 32 bits, so watch out for overflow occuring near $2 million or $20 million, depending on whether the integers represent mils or cents. I believe it may be possible for PHP to give an incorrect result without an error condition for some integer overflow conditions.
