Vb. The division operator in net and the division operator in C #

Vb. The Division operators in net have two:/(floating-point division), \ (integer division)

The division operator in C # has only one:/(Division)

Vb. The division operator in net differs greatly from the division operator in C # , and is differentiated when used.

Introduction to the division operator in vb.net (from MSDN):

/(Floating point Division): divides two numbers and returns the result expressed as a floating-point number.

The data type of the resulting result depends on the type of the operand. The following table shows how to determine the data type of the result.

Operand data type	Result data type
Two expressions are integer data types (SByte, Byte, Short, UShort, Integer, UInteger, Long, ULong)	Double
One expression is a single data type and the other expression is not Double	Single
One expression is a Decimal data type and the other expression is not single or Double	Decimal
Either expression is a Double data type	Double

Any integer numeric expression will be extended to Double before the division is performed. If you assign the result to an integer data type, Visual Basic attempts to convert the result from a Double to this type. If the result does not fit the type, an exception is thrown. If DivisorOr DividendThe result of the calculation equals nothing, it is treated as zero. \ (integer division): divides two numbers and returns the result expressed as an integer. The following table determines the data type of the result. Note that this table is symmetric, and for a given operand data type combination, the result data type is the same regardless of the order of the operands.

	Boolean	SByte	Byte	Short	UShort	Integer	UInteger	Long	ULong
Boolean	Boolean	SByte	Short	Short	Integer	Integer	Long	Long	Long
SByte	SByte	SByte	Short	Short	Integer	Integer	Long	Long	Long
Byte	Short	Short	Byte	Short	UShort	Integer	UInteger	Long	ULong
Short	Short	Short	Short	Short	Integer	Integer	Long	Long	Long
UShort	Integer	Integer	UShort	Integer	UShort	Integer	UInteger	Long	ULong
Integer	Integer	Integer	Integer	Integer	Integer	Integer	Long	Long	Long
UInteger	Long	Long	UInteger	Long	UInteger	Long	UInteger	Long	ULong
Long	Long	Long	Long	Long	Long	Long	Long	Long	Long
ULong	Long	Long	ULong	Long	ULong	Long	ULong	Long	ULong

If any of the two operands of the \ operator is a Decimal, single, or Double, Visual Basic attempts to convert it to long before the operation, and the result data type of the operation is long. If Option Strict is on, a compiler error is generated. If Option Strict is Off, OverflowException may be generated if the value exceeds the range of the Long data type (Visual Basic). The conversion to Long also obeys "four homes six into 50% pairs". If the divisor or dividend evaluates to nothing, it is treated as zero.

An introduction to the division operators in C # (from MSDN):

/(Division): divides two numbers and returns the data type with high precision in the data type of divisor and dividend.

Before the division is performed, the compiler unifies the data types of the divisor and dividend into high precision data types in both types. The type of the result of the returned operation is also a data type with high precision in both types. For example, the result of dividing two integers is always an integer. Divides an integer and a double, returning the result to a double type. However, it is important to note that double and decimal do not perform arithmetic operations directly, they must first be explicitly unified before they can be performed, and double and decimal cannot be directly operated because there is no implicit type conversion between the two.
