Two numbers, and set the number of digits of the decimal number Function Wxchu ($ LEFT, $ RIGHT, $ Num = 0) {
IF ($ right) {
$ ping = $ ip / $ right;
IF ($ NUM) {$ TEMP = FLOOR ($ ping);
Else {$ Temp = Substr ($ ping, 0, strpos ($ ping, ".") $ NUM 1);
} else {$ TEMP = 0;}
Return $ TEMP;
}
$ LEFT is the number of bits that $ RIGHT for the divisted $ NUM to take a small number, if not set, no decimal
