int 能表示最大的正整数是 0x7FFFFFFF 超过这个数，就需要用unsigned int 表示，或者用64位的 long long 表示。对于C/C++ ObjC里面，一般用于关键结构体定义的 数字变量类型 都用最流行的一套宏定义，大概就是下面这个写法 int8_t int16_t int32_t int64_t uint8_t uint16_t uint32_t ...

Implicit conversion loses integer precision: 'NSInteger' (aka 'long') to 'int. City:[bpDictionary objectForKey:@"timeLineVideoUserName"] Address:[bpDictionary objectForKey:@"timeLineVideoDetails"]]; [self.objectHolderArray addObject:currenHotel]; } How can I solve this problem? In HotelObject'...
I am using XC8 free compiler from Microchip, v1.45. When I do this, it gave me warning: jumper.c:54: warning: (373) implicit signed to unsigned conversion Code: uint8_t mask = 0; // do some stuff to mask LATF = ~mask; When I do this, it won't complain: Code: uint8_t...
1. 解释implicit conversion from 'enum <anonymous>' to 'gpio_id'错误的含义 这个错误表明编译器在尝试将一个匿名枚举(enum <anonymous>)的值隐式转换为gpio_id类型时遇到了问题。在C或C++中,枚举类型默认是整数类型,但如果枚举类型与gpio_id类型(可能是一个整数类型但具有不同的底层表示或范围...
符合規範的替代項目為 Implicit(Int32 to BigInteger)。 C# 複製 [System.CLSCompliant(false)] public static implicit operator System.Numerics.BigInteger (ushort value); 參數 value UInt16 要轉換為 BigInteger 的值。 傳回 BigInteger 物件,包含 value 參數的值。 屬性 CLSCompliantAttribute 備註 對於不...
