decimal data type teradata

When you preserve decimal type data by System.Data.Entity.DbContext, only the decimal place 2 bits is reserved by default. To solve this problem, you can add the appropriate code in the Onmodelcreating event, and refer to the following code for the shop. The longitude is set to 20 bits of

other two functions are used to convert a string to a value. ParseInt (string) function: converts a string to a numeric value without rounding. Here, the string must be a string starting with a number. It is not stopped until it is traversed to the character of a non-numeric value. If it is not the beginning of a number, NaN is displayed. The execution result is: 123,124,234, NaN. ParseFloat (string): converts a string to a floating point number. Starting from the digit bit and ending with a n
