file – String format procedure similar to writeln – Stack Overflow

Posted by jpluimers on 2021/05/11

Cool Format feature from [WayBack] file – String format procedure similar to writeln – Stack Overflow:

The cool thing about using Format is that you use for Format Strings not only to parameterize things like width and precision inside that Format String, but also as paramaters like you normally would provide values.

You can get very close to using a width of 8 and a precision of 2, like the example in your question.

For instance, to quote the documentation:

Format ('%*.*f', [8, 2, 123.456]);

is equivalent to:

Format ('%8.2f', [123.456]);

That is a much overlooked feature of Format and Format Strings.
