bccomp (PHP 3, PHP 4, PHP 5) bccomp -- Compare two arbitrary precision numbers Descriptionint bccomp ( string left_operand, string right_operand [, int scale] )
Compares the left_operand to the
right_operand and returns the result as an
integer. The optional scale parameter is
used to set the number of digits after the decimal place which
will be used in the comparison. The return value is 0 if the two
operands are equal. If the left_operand
is larger than the right_operand the
return value is +1 and if the left_operand
is less than the right_operand the return
value is -1.
