Section 1.5 Display Formats
One can control the format in which MATLAB displays (echos) output to the command window:
-
The default format is fixed-point with 4 decimal digits.
-
Issue the format command (see below for some examples) to change the output for the remainder of the session.
-
The output format does not change the way that MATLAB computes and stores numbers.
-
The default data type is a double-precision array which means that by default, any number is stored with double-precision (which means using 64 bits).
-
Using 64 bits, number you can store range from 2.225073858507201e-308 to 1.797693134862316e+308

| Display Format | Description | Example |
| format short | fixed-point with 4 decimal digits for \(0.001 \leq\) number \(\leq 1000\text{,}\) otherwise uses short e
|
>> 290/7 ans = 41.4286 |
| format long | fixed-point with 15 decimal digits for \(0.001 \leq\) number \(\leq 1000\text{,}\) otherwise uses long e
|
>> 290/7 ans = 41.42857142857143
|
| format short e | scientific notation with 4-decimal digits
|
>> 290/7 ans = 4.1429e+001
|
| format long e | scientific notation with 15-decimal digits
|
>> 290/7 ans = 4.142857142857143e+001
|
| format short g | best of 5-digit or scientific notation
|
>> 290/7 ans = 41.429
|
| format long g | best of 15-digit or scientific notation
|
>> 290/7 ans = 41.4285714285714
|
| format bank | Two decimal digits
|
>> 290/7 ans = 41.43
|
| format compact | eliminates empty lines
|
|
| format loose | adds empty lines
