How many exact decimals can offer Matlab?
Show older comments
Hi, everybody. I would like to know how many exact decimals can offer Matlab. I did a program to calculate Viete sums and run it and I can see only 4 exact decimals in the answers. Thats all matlab can offer or there is a setting where I can change precision? Thank you, Daniela

If you type
>> format long
you will see about 15 digits of precision. By default, MATLAB does numerical calculations on double-precision floating point numbers, but uses the "short" display format. You can read a bit more with
>> doc format
There is a lot more that can be said, but maybe that's enough for you to know to start?
