I have one problem related to double data type .

dou=0.0000454444
when i convert this to string it shows the value in exponential like this

Value is changing in run time even i do not cross the precision of double .I want to be my answer in double format .
Anyone know this problem please help me .I have applied all things.

The approach suggested by Sen M should work fine. In factif you increase the number of #'s to 15 it should suppress exponential format for any decimal number: string format = 0.###############; double dou = 0.0000454444; MessageBox.Show(dou.ToString(format)); If you don't do this then the ToString() method uses the G format by default which displays double precision numbers in exponential format if their absolute value is 0.00001 or less as Manish implied.
