The syntax of a format sequence is follows. The precision specifies the number of digits after the decimal point defaulting to six. The precision specifies the number of significant digits. The number of characters written, or -1 if an error occurred. If buffer or format is a null pointer, the invalid parameter handler is invoked, as described in Parameter Validation.

The sprintf function formats and stores a series of characters and values in buffer. Each argument if any is converted and output according to the corresponding format specification in format. The format consists of ordinary characters and has the same form and function as the format argument for printf. A null character is appended after the last character written. If copying occurs between strings that overlap, the behavior is undefined. Using sprintf , there is no way to limit the number of characters written, which means that code using sprintf is susceptible to buffer overruns.

Also, ensure that format is not a user-defined string. The argument is interpreted as a short int or unsigned short int only applies to integer specifiers: i, d, o, u, x and X.

The argument is interpreted as a long int or unsigned long int for integer specifiers i, d, o, u, x and X , and as a wide character or wide character string for specifiers c and s. If successful, the total number of characters written is returned excluding the null-character appended at the end of the string, otherwise a negative number is returned in case of failure.

Otherwise, str is a character vector. To return multiple pieces of formatted text as a string array or a cell array of character vectors, use the compose function.

Otherwise, errmsg is empty. It returns all other characters unaltered. To return formatted text as a string, specify formatSpec as a string instead of a character vector when you call the sprintf function. Starting in Ra, you can create strings using double quotes. Convert data and return the result as a string. Format of the output fields, specified using formatting operators. The conversion character is required. Spaces are invalid between operators and are shown here only for readability.

Base 16 hexadecimal , lowercase letters a — f. Fixed-point notation Use a precision operator to specify the number of digits after the decimal point. Exponential notation, such as 3. Character vector or string array.

The type of the output text is the same as the type of formatSpec. The optional identifier, flags, field width, precision, and subtype operators further define the format of the output text.

Order for processing the function input arguments. Note: If an input argument is an array, you cannot use identifiers to specify particular array elements from that input argument. Insert a space before the value. Pad to field width with zeros before the value. Minimum number of characters to print.
