Functions

tcng currently only has one function: the formatted output function sprintf that returns a string, like the function with the same name in Perl.

The usage is like in C or Perl, and the following components are recognized in a conversion specification (see section B1.2 of [KR88] for further details):

• a leading - for left adjustment
• 0 for leading zeroes
• the minimum field width, or *
• if the conversion character is f or s: the precision, or *
• the conversion characters d, u, o, x, X, f, c, s, and %

When using the conversion character %, the whole specification must be %%.

Example:

$tag = "item"+sprintf("%04d",$number);
