6.58 Other Built-in Functions Provided by GCC(点击打开链接)这个页面最后面三个函数就是我们需要的: — Built-in Function: uint16_t __builtin_bswap16 (uint16_t x) Returns x with the order of the bytes reversed; for example, 0xaabb becomes 0xbbaa. Byte here always means exactly 8 bits./...
Example In this example, we take an integer value in variablea. We try to get help for this variableausing help() function. Python Program </> Copy a=2help(a) Output Help on int object: class int(object) | int([x]) -> integer | int(x, base=10) -> integer | | Convert a ...
The user can use cast function to convert column values or literal constants into other types required by function parameters.Example:mysql> select concat('Here are the first ', cast(10 as string), ' results.'); +---+ | concat('Here are the first ', CAST(10 AS CHARACTER), ' results...

内建函数 Build-in Function,启动python解释器,输入dir(__builtins__), 可以看到很多python解释器启动后默认加载的属性和函数,这些函数称之为内建函数, 这些函数因为在编程时使用较多,cpython解释器用c语言实现了这些函数,启动解释器 时默认加载。 这些
How to use the INDEX function to find data in a table OFFSET() and MATCH() You can use theOFFSETandMATCHfunctions together to produce the same results as the functions in the previous example. The following is an example of syntax that combinesOFFSE...
ReturnType = FunctionName(Expression) The Expression could be of any kind. For example, it could be a string or value the user would have entered in a form. It could also be the result of a calculation performed on another field or function. The conversion function would take such a valu...
Matrices may be transposed using the built-in transpose() function. If you transpose a non-square matrix, its dimensions are simply swapped. transpose函数可以用来把一个矩阵进行转置,如果你转置的是一个非方阵,那么行数和列数与原始的矩阵是互换了的。 To find the inverse of a matrix, GLSL provides...
