[델파이] Format

'%' [[Index]':'] ['-'] [Width] ['.' Precision] ArgType

'%'	starts the placeholder. If you want to insert a literal % character, then you must insert two of them : %%.
Index ':'	takes the Index-th element in the argument array as the element to insert. If index is omitted, then the zeroth argument is taken.
'-'	tells Format to left-align the inserted text. The default behaviour is to right-align inserted text. This can only take effect if the Width element is also specified.
Width	the inserted string must have at least Width characters. If not, the inserted string will be padded with spaces. By default, the string is left-padded, resulting in a right-aligned string. This behaviour can be changed by the usage of the '-' character.
'.' Precision	Indicates the precision to be used when converting the argument. The exact meaning of this parameter depends on ArgType.
