A floating point type is characterised by its (decimal) digits which state the minimal precision requested. type Distance is digits 8; Earth : Distance := 40_075.017;

A fixed point type definition specifies a delta, and a range. Together, they describe how precisely real values should be approximated as they are represented by powers of two, not using floating point hardware. Shoe_Ounce : constant := 2.54 / 64.0; type Thickness is delta Shoe_Ounce range 0.00 .....

Decimal fixed point types are typically used in accounting. They are characterised by both a delta and a number of decimal digits. Their arithmetical operations reflect the rules of accounting. type Money is delta 0.001 digits 10; Oil_Price : Money := 56.402; Loss : Money := 0.002 / 3; -- ...

If you're accepting user input for folder paths, you might need to check for trailing backslashes (\) before building a file path. The FSO.BuildPath method makes this simpler: Const sourceFilePath As String = "C:\Temp" '<-- Without trailing backslash Const targetFilePath As Strin...

Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone. #include <iostream> int main() { using std::cout; cout << "Hello, world!\n"; }

If a using-declaration occurs at class scope, it is only allowed to redeclare a member of a base class. For example, using std::cout is not allowed at class scope. Often, the name redeclared is one that would otherwise be hidden. For example, in the below code, d1.foo only refers to Derived1::foo(c...

Block will capture variables that appeared in the same lexical scope. Normally these variables are captured as "const" value: int val = 10; void (^blk)(void) = ^{ val = 20; // Error! val is a constant value and cannot be modified! }; In order to modify the variable, you need to ...
