Reading 1.999999 from excel when the value is 2

Hi Gurus,

I have observed a weird thing with excel source in SSIS. I was reading few file yesterday and I observed that it is reading as 1.99999 for 2 value like for other values too. I thought rounding up that col but I have been told I might be getting values like 1.1.1.1 in that col in the future Like:

Col1

1
1.1
1.2
1.3

In future I might get values like

col1

1
1.1
1.1.1
1.2
1.2.1 etc.

Please help me how to load the right values into db.
