Toad truncating/rounding large Oracle numbers?

Question

We have a table with a 'price' field of type NUMBER(20,7).. In TOAD I do this:

update mytable set price = 1234567890123.1234567;

Then I do this select:

select price, to_char(price) from mytable

PRICE              TO_CHAR(PRICE)
1234567890123.12   "1234567890123.1234567"

Question is, why does TOAD truncate the result when displaying the NUMBER(20,7) field? The data is obviously there as it prints out with to_char.

Answer 1

Toad limits numbers in the data grid to 15 digits. I believe this is because excel limits numbers to 15 digits as well (or used to limit them). You can turn on "scientific notation" in options -> data grids -> data, check box Display large numbers in scientific notation. That won't probably help, either.
