Import rounding CSV data to 3 places

I’m importing a CSV file to do some data work, but the imported data is either rounded to three digits. For example,

Imported data
time
-75.1
-25.1
-5.53
7.43
17.9
65.7
123
558
767
1130
1240

CSV data file
time
-75.1245
-25.152345
-5.535432
7.4323456
17.92345
65.75423
123.5234
558.6534
767.6547
1134.2346
1242.23456

How can I get the data in full or control the rounding? I’m importing simply as shown below.

allData = Import["C:\\data.csv"];

Thanks in advance.

Please run the function InputForm on allData:

InputForm[allData]

Mathematica often stores numbers at a higher precision than it displays them. This helps to keep things readable in many situations.

Thanks for the reply Sean.

According to that check, the data is as I posted the first time, rounded to three digits. It could be due to how Excel is saving the data. I just checked in notepad and found everything is in sci notation (rounded to… hundredths place). Even though Excel can re-open the file and I can see all the original decimal places, it appears other programs are not equally able. Time to do some guessing.
