The double data type in C is primarily used to store high-precision floating-point numbers in the computer's memory. The term 'double' signifies that it can hold twice the amount of data compared to the float data type. A double data type consists of 8 bytes (64 bits) of data. Out ...
double is the default numeric data type (class) in MATLAB®, providing sufficient precision for most computational tasks. Numeric variables are automatically stored as 64-bit (8-byte) double-precision floating-point values. For example: x = 10; whos x Name Size Bytes Class Attributes x 1x1 ...
UNIONTYPE - 类似于C语言的unions,一个UNIONTYPE可以有指定的data types的任意一种 例如:声明一列为Union Type CREATE TABLE test(col1 UNIONTYPE<INT, DOUBLE, ARRAY<VARCHAR>, STRUCT>); 1. 从col1中获取值如下: SELECT col1 FROM test; {0:1} // Matching...

首先看一下sizeof在msdn上的定义: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of type size_t. 看到return这个字眼,是不是想到了函数?错了,sizeof不是一个函数,你见过给一个函数传参数,...
