floating point question

Hello. I imported a .csv file to into matlab which has 10 million rows and 2 columns. I truncated the number of rows to 100 thousand. The first column has doubles but matlab only displays 4 digits after the decimal point. Is there a way to get more digits like 8 or 9?

For example: copy and paste this into your command window:

format short
