Hi,

I have a number like -0.123456.

If I store this in MATLAB, the last 2 digits are rounded off. How to
store such kind of numbers in MATLAB ?

Thanks..

Hi,

Number is stored properly but displayed in such way.
Just do "format long" to check it out.

ps: help format for other formats

By default Matlab uses double precision which has roughly 15 decimal
digits of precision. What your seeing is the result of the display
format. Try
