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

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

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

Vb. NET and the division operator in

Division operators in C #

There is a big difference, the use of attention to distinguish.

)：

/(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 ( , , , , , , , )	Double
An expression of p> data type, while another expression is not	single
One expression is Data type, and another expression is not or	Decimal
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

Divisor

Or

Dividend

The calculated result equals

, 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 one of the \ operator two operands is

、

Or

, Visual Basic attempts to convert it to a

, 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

Divisor

Or

Dividend

The result of the calculation equals nothing, it is treated as zero.

)：

/(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.
