a double number has tihs value: 219.67377380133897
I've tried to change it to string using format strings:
number.ToString("###0.0###############") = 251.673773801339 > (897) changed by 9
number.Tostring("F16") = 219.673773801339000 > (897) changed by 9
Any way to solve this??

Have you tried just .ToString()?

.ToString() doesn't work on all situations, until now this is the only problem I have using string formats.

Where do you think ToString(string) won't work?

A Double value has up to 15 decimal digits of precision, although a maximum of 17 digits is maintained internally, Double structure[^].
As you have found out, many of the format specifiers will only access 15 digits. To see all 17 use the round trip specifier "R" or the general specifier "G17".
