Format rat uses a continued fraction algorithm to approximate floating point values by ratios of small integers.
Format rat matlab.
If you consider the first two terms of the expansion you get the approximation 3 1 7 2 2 7 which only agrees with pi to 2 decimals.
The result is an approximation by continued fractional expansion.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
From the matlab prompt help format format set output format.
Matlab always displays integer data types to the appropriate number of digits for the data type.
To maintain a format across sessions choose a numeric format or line spacing option in the command window preferences.
The specified format applies only to the current matlab session.
The result is an approximation by continued fractional expansion.
Rational approximations are generated by truncating continued fraction expansions.
Remove blank lines around column number labels and between matrices producing more compact output with more data per page.
Matlab always works in double precision unless you are using the symbolic math toolbox but output display can be changed with the format command.
All computations in matlab are done.
Format por sí mismo restablece el formato de salida al valor predeterminado que es el formato corto decimal fijo para la notación de punto flotante y el espaciado de líneas sueltas para todas las lineas de salida.
See rat m for the complete code.
If you consider the first two terms of the expansion you get the approximation 3 1 7 2 2 7 which only agrees with pi to 2 decimals.
The rats function calls rat and returns strings.
The specified format applies only to the current matlab session.
N d rat x returns arrays n and d so that n d approximates x to within the default tolerance 1 e 6 norm x 1.
You can insert a space between short or long and the presentation type for instance format short e.
For example with the rat format pi is displayed as 355 113.
N d rat x tol returns n d approximating x to.
The rat function attempts to do this.
The following two options affect the display of all matrices.
However if you consider all three terms printed by rat you can recover the value 355 113 which agrees with pi to 6 decimals.
