int ou float?


Recommended Posts

Penso que a maneira mais facil será fazer um typecast e comparar:

#include <iostream>

main () {

float v, t;

std::cout << "Introduzir um valor: ";
std::cin >> v;

t = float((int)v);

if (t==v)	//int
	std::cout << v << " e' inteiro" << std::endl;
else		//float
	std::cout << v << " e' float" << std::endl;

Mas atenção aos números grandes, porque a precisão não é infinita...!
