Centro de ayuda Centro de ayuda. El formato de salida depende de las magnitudes de los valores originales. Convierta los valores de punto flotante que devuelven pi y eps a vectores de caracteres. El resultado depende del hardware y el sistema operativo del ordenador. Tipos de datos: single double int8 int16 int32 int64 uint8 uint16 uint32 uint Formato de los campos de salida, especificado con operadores de formato. Vector de caracteres o arreglo de cadena. El tipo de texto de salida es el mismo que el tipo de formatSpec. Los operadores opcionales de identificador, indicador, anchura de campo y subtipo contribuyen a definir el formato del texto de salida. Justifica a la izquierda. Inserta un espacio antes del valor. Rellena la anchura del campo con ceros antes del valor. Puede utilizar un operador de subtipo para imprimir un valor de punto flotante con su valor octal, decimal o hexadecimal. Esta tabla muestra las conversiones que pueden utilizar subtipos.

Create a fi object and convert it to a character vector with 8 digits of precision. Data Types: fi double single int8 int16 int32 int64 uint8 uint16 uint32 uint64 logical Complex Number Support: Yes. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint Format of the output fields, specified using formatting operators.

To display a message that has a quote mark, you need to enter 2 quotes marks, like this: disp 'Lincoln''s birthday is Feb. Concatenation: Connect 2 or more vectors or character strings into a single vector or character string. In order to concatenate a character string with a number, the number needs to be converted to a character string. That can be done with the num2str function. You do not need to know any details about ASCII format, except that it is different than number format. If you want to learn more, see:. The next line of code concatenates the variable name and its value into a single character string:. Part a: For this exercise you will use num2str to disply pi with 3 significant figures and with with 10 significant figures. To do this, you need to read the help on the num2str function.

Format of the output fields, specified using formatting operators. If the number of characters to print is less than the field width, then the compose function pads to the field width with spaces before the value unless otherwise specified by flags. Input Arguments collapse all A — Input array numeric array. Answered: Walter Roberson on 21 Sep Select a Web Site Choose a web site to get translated content where available and see local events and offers. Label with num2str. This table shows how to represent special characters in formatSpec. Show older comments. See Also. Output Arguments collapse all s — Text representation of input array character array. If you specify a precision operator for floating-point values that exceeds the precision of the input numeric data type, the results might not match the input values to the precision you specified. Algorithms num2str trims any leading spaces from a character array, even when formatSpec includes a space character flag.
