Decimal.TryParse

Syntax

TryParse(Value: String; Var Result: Decimal): Boolean;

Value. The string value that must be converted to the Decimal type.

Result. The variable, to which the value in case of successful conversion will be placed.

The TryParse method converts string value into the Decimal type with validation.

If conversion is successful, the method returns True, and the new value is placed into the variable specified in the Result input parameter.

Sub UserProc;
Var
    b: Boolean;
    d: Decimal;
    s: String;
Begin
    s := "234";
    b := Decimal.TryParse(s, d);
End Sub UserProc;

After executing the example in case of successful conversion the "b" variable contains True, and the "d" variable contains the value 234.
