Formats a string and returns it to a variable.
procedure Str(X: Width; var S); overload; procedure Str(X: Decimals; var S); overload;
Str(Width X, S); Str(Decimals X, S);
System
In Delphi code, Str converts X to a string representation according to the Width and Decimals formatting parameters. The effect is like a call to Write except the resulting string is stored in S instead of being written to a text file.
X is an integer-type or real-type expression. Width and Decimals are integer-type expressions. S is a string-type variable or a zero-based character array variable if extended syntax is enabled.
