Description
int 
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.
