代码如下：class Program { static void Main(string[] args) { double datax = 2356987.2156;//声明double类型datax int datay = Convert.ToInt32(datax);//使用convert关键字进行转换 Console.WriteLine(datay);//输出整型变量datay Console.ReadLine(); } }结果与上例一样：...
var pUInt8 = CPointer<UInt8>(pInt8) // CPointer<Int8> convert to CPointer<UInt8> 0 } 仓颉语言支持将一个 CFunc 类型的变量类型转换为一个具体的 CPointer,其中 CPointer 的泛型参数 T 可以是满足 CType 约束的任意类型,使用方式如下: 收起 深色代码主题 复制 foreign func rand(): Int32 main...
我希望将64位值从十进制或十六进制字符串转换为64位UINT64数据类型。有一个UIntToStr来帮助将UINT64转换为string,但无法将64位整数转换为无符号值,即字符串。这意味着,使用RTL不能用十进制或十六进制表示大于2**63的整数值。这通常不是什么大问题,但用户需要输入一个值,作为一个无符号整数,它必须作为6...

如对于：const char * GetString(void);如下语句将出现编译错误：char *str = GetString();//cannot convert from 'const char *' to 'char *'；正确的用法是：const char *str = GetString();b.如果函数返回值采用“值传递方式”，由于函数会把返回值复制到外部临时的存储单元中，加const修饰...
Something that comes up regularly in iPhone development is the need to convertNSNumberobjects toNSStringobjects and vice versa. For converting anNSNumberto anNSString, there is the-stringValuemethod, which is useful if you want just the plain number without any extra formatting. This isn’t parti...
