printf with std::string?
...r example:
std::locale loc("");
std::cout.imbue(loc);
std::cout << 123456.78;
The nameless locale (the "") picks a locale based on the user's configuration. Therefore, on my machine (configured for US English) this prints out as 123,456.78. For somebody who has their computer configured fo...
What does Expression.Quote() do that Expression.Constant() can’t already do?
...) ex1.Compile();
var f1b = f1a(100);
Console.WriteLine(f1b(123));
The lambda has a nested lambda; the compiler generates the interior lambda as a delegate to a function closed over the state of the function generated for the outer lambda. We need consider this case no more.

Round to at most 2 decimal places (only if necessary)

If the value is a text type:
parseFloat("123.456").toFixed(2);
If the value is a number:
var numb = 123.23454;
numb = numb.toFixed(2);
There is a downside that values like 1.5 will give "1.50" as the output. A fix suggested by @minitech:
var numb = 1.5;
numb = +nu...
