There are two types of type conversion: Implicit type conversion. Explicit type conversion. 2021-03-08 2020-04-30 Implicit conversions. For built-in numeric types, an implicit conversion can be made when the value to be stored can fit into the variable without being truncated or rounded off. For integral types, this means the range of the source type is a proper subset of the range for the target type.
Here are some common methods of explicit conversions. However, because implicit conversions do not require programmers to explicitly cast from one type to the other, care must be taken to prevent unexpected results. In general, implicit conversion operators should never throw exceptions and never lose information so that they can be used safely without the programmer’s awareness. The conversion from an unscoped enumeration type to an arithmetic type is an implicit conversion; it is possible, but not necessary, to use static_cast.

Comparison of JSON values takes place at two levels.

For example, are conversions from smaller to larger integral types and conversions from derived classes to base classes. An implicit conversion from type S to type T is defined by an implicit value which has function type S => T, or by an implicit method convertible to a value of that type. Implicit conversions are applied in two situations: If an expression e is of type S, and S does not conform to the expression’s expected type T. Implicit Type Conversion If the type conversion is conducted instantly through compiler without having the programmer’s involvement, the type conversion is known as implicit type conversion. Implicit conversion of a numeric or temporal value to string produces a value that has a character set and collation determined by the character_set_connection and collation_connection system variables.

The first level of comparison is based on the JSON types of the compared values. Type Conversions In Expressions| Implicit Type Conversion | Explicit Conversions
C# allows you to augment the pre-defined implicit and explicit conversions, these are called user-defined conversions. They can be introduced by declaring conversion operators in class and struct types.

For example Pascal is strongly typed and forces the programmer to explicitly convert. On the other hand VBScript pretty much converts anything to anything. BOL clearly outlines T-SQL rules for data type implicit conversions. There are two ways to define implicit type conversion.
