Hi,
in C language you can use longfloat command..
E.g., try %12.10lf command and see the result..

It looks like your using a single (BASIC) or a short float (C) type variable.

As others have mentioned use a double (BASIC) or a double (C) or long double when defining the variable. Also as others have mentioned make sure the print instruction converts the variable to the right format (double or long double) so that you don't get the truncation that is occurring.
