Core Function Fmt

Fmt( <expression>, <expressions>... )

Description

Create a formatted string.

expression

The format string and flags to use (see Remarks).

expressions

Variables that will be output according to the "Format Control".

Return Value

Success: Returns the formatted string.

Failure: Returns an empty string.

Remarks

If you are looking for something that works similar to C's sprintf() function see this SPrintf( <format control>, <params> )

Warning: If you expect to use int, byte, float etc in the params then you must cast it as such for example:

$myint = 100;
$val = fmt("Value is 0x\{0:x}", (int)$myint); // The (int) will only take in $myint
println($val);
 
$myint = 100;
$myint2 = 100;
$val = fmt("Value is 0x\{0:x}", (int)($myint + $myint2)); // The (int) will now take in $myint AND $myint2
println($val);

Note how $myint was cast as an int? using (int)$myint this is vital since if you dont do that it might send a string or a float you never really know with $variables so its best to cast it.

There is an alternative method example:

$myint = 100;
$val = fmt("Value is 0x\{0:x}", int($myint));

Its up to you to decide which one to use.

Go see PrintfC( <expression>, <expressions>... ) for details on the format string

Anything thats valid for PrintfC to print to console window is also valid for Fmt to use to create strings.

Example

$val = fmt("Value is '0x\{0:x}'", (int)100);
println($val); // Prints 0x64 since the {0:x} is telling it to place param 0 as :x meaning hex
