cast

• Functionality

  Casting can be done if you want to switch from one type to another. You can switch to either double or string types.

• Arguments

  No arguments needed.

• Return

  The type to which cast is intended.

• Conditions

  No condition.

• Examples

  (Double) '12' returns a double type with the value 12.

• Exceptions

  Exceptions can appear if you want to cast to a double value from a string value and the string value contains any non-number values. E.g. this cast doesn't work : (double) '1231ewq'.
