Inside the loop, we perform the type conversion using a C-style cast: int(f). As we can see in the output, this cast converts the floating-point number f to its integer representation. In practice, when possible, it’s better to use more type-safe casting mechanisms provided by C++,...
意思是从浮点型转换为整型，可能会丢失数据

x=c把float转换成int了
abs 的参数是 int，你a,b是浮点，所以有这警告。另外 while(abs(a)>=0, abs(b)>=0)里的逗号是不是应该修正下？
Use thestd::to_string()function to convert the float to a string. Let’s explore the basics of using theto_stringfunction for numeric-to-string conversion: #include<iostream>#include<string>using std::cout;using std::endl;using std::string;intmain(){floatn1=123.456;doublen2=0.456;doublen3...

1、从int是表达很精确的类型，而float不是，因此从int转换到float确实会出现上述的warning；2、这里之所以会出现，是因为：“整数/整数”是一个整除，结果仍旧是整数，除不尽的会丢弃；然后再将一个整数结果赋值给float，于是warning出现了；直接消除的方法就是强制类型转换：average=(float)(sum/3);这...
Further, I find that when converting from float to unsigned long, the compiler _sometimes_ generates code that converts any value above UINT_MAX/2 to UINT_MAX/2. The following code:#include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]){unsigned long r = 1;float f = 3.0e9;...
