Fetching Double Value from SQLite in iOS -

-

though may seems simple, trying hours on this.

hello, everyone, storing double value in sqlite database in ipad application.

sqlite database image field containing double values

i fetching records using simple "select * tablename" query.

then converting patient_dos value double.

but prints when display content of first patient dictionary.

"patient_dos" = "1461561219160.408936";

and below value after converting value in double variable using following conversion method.

double p_dos = [[dict objectforkey:@"patient_dos"] doublevalue];

result 

printing description of p_dos: (double) p_dos = 1461561767624.27

my main concern match double, timestamp, of day when patient admitted without hh:mm:ss information.

update: added data type image.

you can convert string (which database) double like,

nsstring *str = @"1461561219160.408936";  double fl = [str doublevalue];  nslog(@"double vvalue : %f",fl);

this printing exact 1461561219160.408936 in console
