No effect if data still remains on the list. Terminates format processing if no more items remain in the argument list. For example, if your data reside in tables of the following form: 26.01 92.555 344.2 101.0 6.123 99.845 23.723 200.02 141.93Įnsures that the correct number of digits are read or output for each element. Using a value of zero for the width parameter is useful when reading tables of data in which individual elements may be of varying lengths. The value is read or output using a default format without any leading or trailing whitespace, in the style of the standard C library printf() function.
If the numeral zero is specified for the width parameter, IDL uses the “natural” width for the value.
