Hello,
1) maybe someone knows how to put into variable 3 last decimal numbers of price?
For example:
1.44550; &variable=550
159.333; &variable=333
1.92131; &variable=131
2) how to put into variable first 4 characters of a price? (including a point)
examples:
1.44550; &variable="1.44"
159.333; &variable="159."
1.92131; &variable="1.92"

int bid = Bid / Point + 0.5;
int last = bid % 1000;
int first = bid / 1000;
