long long get_ms(void) { long long ms = 0; struct timespec s; clock_gettime(CLOCK_MONOTONIC, &s); ms = (long long)s.tv_sec*1000 + s.tv_nsec/1000000; return ms; } 这个代码的问题在于类型转换的写法。 代码本身已经意识到了32bit的数据类型
C++ is a strong-typed language. Many conversions, specially those that imply a different interpretation of the value, require an explicit conversion. We have already seen two notations for explicit type conversion: functional and c-like casting: The functionality of these explicit conversion operators...

In the C programming language – a positive integer value (int) can be assigned in an unsigned integer (unsigned intoruint) automatically (implicit type conversion). But in the Go language, this assignment will not happen. See the below examples (C language code & Go language code) demonstrat...
The conduct of General Tilney in expelling Catherine Morland fromhis home without notice, and for no good reason, has been a difficult crux for many readers of Northanger Abbey. Others, however, have taken it in their stride. Ambiguities appear to arise from the characterisation of the General...
This is the same as in the Java programming language. Now we will see how it can be improved.Save the above program in Demo.scala. The following commands are used to compile and execute this program.Command\>scalac Demo.scala \>scala Demo ...
In the <stdlib.h> there are few interesting functions that could be used to convert data types: atof(charArray) will transform the array in style of C language into float. atoi(charArray) will transform the array of chars into the int. ...
System.Int32 is the name of the underlying data type in the .NET Class Library that the C# programming language maps to the keyword int. Because the Convert class is also part of the .NET Class Library, it is called by its full name, not its C# name. By defining data types as part...

A plastics pocket-type bearing cage for radial cylindrical roller bearings having elastically deformable holding projections (5) arranged on the cage webs (3) is produced in an injection mould or casting mould provided with radial slide bars (1). In order that the weld line elevation does not...
