Vb. The Division operators in net have two:/(floating-point division), \ (integer division)
The division operator in C # has only one:/(Division)

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.

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 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.
