编译器对我有关类型转换的方法做了什么

Question

Hey, I appreciate if you could tell me what the compiler does on my method. If I call it with Area(10.1,10.1); it returns me 102 . So the .01 get cut? Do you have a good site where I can get information about this particular topic? thx for your time!

float Area (float length, float width){
int result;
result = length*width;
return result;
}

由于将浮点表达式的值分配给int，因此分配时数据会被截断（但在计算表达式之后）。
