![]() In this example, we will take the same example as we used above for better understanding. Let us now see the code to use the format function for longEng type in Matlab. In this example, we will take the division of 2 integers and will use the format function to get the output in long format.Īs we can see, we have obtained our output in 15 digits because we used ‘long’ as a type for the format function. Given below are the examples mentioned: Example #1 longG: It displays the output in either scientific notation or in fixed decimal format, depending upon which format is more compact.This also causes complex numbers to be formatted as numeric. longE: 15 digits are displayed in scientific notation. Print output in free format, without trying to line up columns of matrices on the decimal point.longEng: 15 digits and an exponential, which is a multiple of three.long: 15 digits are displayed after the decimal point.The argument for the precision field parameter then follows the argument for the value to be formatted. The required value is then provided by an argument (permissible types: BYTE, WORD, DWORD, USINT, UINT, UDINT). The precision field parameter specifies how many characters from the argument string are output.Ĭharacters exceeding the precision value are not output.Īll characters up to the final zero are output.Īn asterisk (*) can also be entered for the precision field parameter. The argument value is always rounded to the respective number of decimal places. The precision field parameter specifies the number of decimal places. If there are not enough digits, the string is filled with zeros from the left. The precision field parameter specifies how many decimal characters (digits) are output in the output string. If the dot is not followed by a value, the default precision value is used (see table). The precision field follows the dot (.) and contains a positive decimal value. The standard C prefix type can be activated by setting the global variable GLOBAL_FORMAT_HASH_PREFIX_TYPE in the program: GLOBAL_FORMAT_HASH_PREFIX_TYPE := HASHPREFIX_STDC Only in conjunction with b, B, o, O, x, X, otherwise the flag is ignored. The blank flag is also ignored if the left sign flag (+) was set at the same timeĪn IEC or standard C prefix is placed before the formatted value. Only in conjunction with e, E, f, F, d, D, otherwise the flag is ignored. ![]() The zero flag will also be ignored if the left-alignment flag (-) is additionally set. Only in conjunction with e, E, f, F, s, S, otherwise the flag is ignored. If this flag precedes the Width parameter, the resulting string is filled with zeros from the left until the required width is reached. The negative sign only appears for negative values. Only in conjunction with e, E, f, F, d,D, otherwise the flag is ignored. The formatted value is left aligned within the width aligned in parameter Width.Ĭan be used in conjunction with all types.įorces output of the positive sign for signed positive numbers. The flag field parameters specify the alignment of the formatted value, the output of signs, spaces and the binary/octal/hex prefixes. One or more flags can be specified in any desired order in the flag field. Reserved for future use.įloating point numbers in scientific notationġ The content of the REAL variable is returned as a binary, octal, hexadecimal or decimal string.Ģ The content of the signed types is returned as a binary, octal, hexadecimal or decimal string.ģ The REAL variable is converted to the LREAL type and then formatted. Lower case letters ('abcdef') are used for formatting. Upper case letters ('ABCDEF') are used for formatting. The sign only appears for negative values.Ĭharacters are output until the final zero or the precision field parameter has been reached. To display data to one decimal place in a uitable, create the table column as char and write pre-formatted strings in to the cells. If the length of the formatted string exceeds the maximum permissible length of the resulting string, '#OVF' or '-#OVF' is returned.īYTE, WORD, DWORD, SINT, INT, DINT, USINT, UINT, UDINT If the variable transferred has an illegal value (NaN, Not-a-Number), '#QNAN' or '-#QNAN' is returned. '#INF' is returned for an infinite positive value and '-#INF' for an infinite negative value. The sign only appears for negative values. The number of digits after the decimal point depends on the required precision. The number of digits before the decimal point depends on the value of the floating point number. The string has the form dddd.dddd, (dddd are decimal numbers). Note that some type field parameters are case-sensitive.īYTE, WORD, DWORD, REAL 1,SINT 2, INT 2, DINT 2, USINT, UINT, UDINTīYTE, WORD, DWORD, SINT 2, INT 2, DINT 2, USINT, UINT, UDINT ![]() The type field contains an ASCII character, which specifies whether the associated argument is interpreted as a string, an integer or a floating point number.
