What is narrowing in VB net?

You use a narrowing conversion when you know the source value can be converted to the destination data type without error or data loss. For example, if you have a String that you know contains either “True” or “False,” you can use the CBool keyword to convert it to Boolean .

What is a narrowing conversion?

A narrowing conversion is an implicit conversion. (7.4) — from an integer type or unscoped enumeration type to an integer type that cannot represent all the values of the original type, except where the source is a constant expression whose value after integral promotions will fit into the target type.

Which casting happens when a narrowing conversion occurs?

Narrowing Conversions (Explicit Casting) This is not done implicitly by the JVM and requires explicit casting . In above example a double variable(8 Byte) converted into integer variable (4 Byte) . The casting happened from a higher data type to a lower data type, so can result in loss of information.

What is the result of narrowing the conversion?

Answer: narrowing conversion changes a value to a data type that might not be able to hold some of the possible values. For example, a fractional value is rounded when it is converted to an integral type, and a numeric type being converted to Boolean is reduced to either True or False .

How is a narrowing conversion carried out in VB.NET?

A Narrowing conversion is one that casts data from a wider data type to a narrower data type. In explicit conversion we specifically ask the compiler to convert the value into another data type. CLR checks for data compatibility at runtime. Explicit conversion is carried out using casts.

What happens when you do a narrowing conversion?

A narrowing conversion changes a value to a data type that might not be able to hold some of the possible values.

When do you use narrowing conversions in Excel?

When to Use Narrowing Conversions. You use a narrowing conversion when you know the source value can be converted to the destination data type without error or data loss. For example, if you have a String that you know contains either “True” or “False,” you can use the CBool keyword to convert it to Boolean.
