In the 3D world, we need to constantly convert coordinates in various spaces. For example, we need to convert an object from a model space to a world space, and convert points in a world space to a view space of a camera. We know that coordinate conversion can be achieved by multiplying a vector and a conversion matrix. Note that if the row vector is selected, the matrix is placed on the right side of the m

EF6 + SQLite3 database type conversion failure (the specified conversion is invalid), ef6sqlite3
The reason for this problem is that all columns of this model in the database are null, so the conversion fails here.
However, I set the value of null in the database (otherwise, the value of null cannot be set), and then generate a model based on the database i
1001. Temperature conversion, 1001 temperature conversion
The description converts the input Fahrenheit temperature to the Celsius temperature. The conversion formula from F to C is F = C × 9/5 + 32.
Input a real number to indicate the Fahrenheit temperature.
Output the corresponding temperature in Celsius. The answer is to keep four decimal place

Convert decimal to binary, octal, and hexadecimal
To convert from decimal to other hexadecimal values, the number is used to continuously divide by the number of hexadecimal values to be converted and read the remainder. Connect them together.
Copy codeThe Code is as follows: /**
* Convert decimal to binary, octal, or hexadecimal with zero padding before the digits being insufficient *
*
* @ Param array $ datalist input data array (100,123,130)
* @ Param int $ bin
