当然,由于内置的除法(built-in operator/)对于只要有浮点数参加的运算,会把所有的操作数都转化为浮点数,所以这样就可以了:float c = (float)a / b;;float c = static_cast<float>(a) / b;。---另外 wolinxuebin 错误。c是float类型,不表示后面的operator/就是浮点除法,两者无关。而且...
Direct assignment (using the assignment operator) is a straightforward method to truncate a float to an int in C++. When you directly assign a float variable to an int variable, the C++ compiler automatically truncates the value by removing the decimal part and retaining only the whole number....
❮ C 语言实例使用sizeof 操作符计算int, float, double 和 char四种变量字节大小。sizeof 是 C 语言的一种单目操作符,如C语言的其他操作符++、--等,它并不是函数。sizeof 操作符以字节形式给出了其操作数的存储大小。实例 #include <stdio.h> int main() { int integerType; float floatType; double...
自加++自减--运算的数据类型可以是Float和Double。在c语言中,并不是所有变量都可以使用自增自减操作符;可以使用自增自减操作符的数据类型有:int、float、double 、char、long。自增(++) :将变量的值加1,分前缀式(如++i) 和后缀式(如i++) 。前缀式是先加1再使用;后缀式是先使用再加1...

main.c: In function ‘main’: main.c:8:22: error: invalid operands to binary % (have ‘float’ and ‘float’) float result = x % y; ^ See the output – it says that invalid operands to modulus operator. How to find the remainder/modulus of two float or double numbers in C?
float c = static_cast<float>(a) / static_cast<float>(b);;前者和C语言兼容(注意LZ的版本不兼容);后者虽然罗嗦,不过清楚,容易通过查找关键字找到转换处。当然,由于内置的除法(built-in operator/)对于只要有浮点数参加的运算,会把所有的操作数都转化为浮点数,所以这样就可以了:float c ...
