WebMay 18, 2024 · 例： float a = 1.5; float b = 1.5f; 常浮点数默认是double型的，当1.5赋值给a时，存在（double）1.5 --> float a的强制转换，当数据较小时，结果一般不会出现错误，当数据较大时，若将右值赋值给左值时产生溢出，结果就会出现非预期值，所以在书写时，最好在常量的末尾加后缀进行严格的限制。 WebThe problem is that .5 and .5f represent different types, which take up different amounts of memory (thus offering different precision). If you mix and match these types the compiler wants to make sure you know what you're doing by giving you a warning. The float literal is also used in C++ to explicitly state a number to be a float.
