Thread: validating a float

Is the an easier way, i get errors here

Code:

bool valid::validFloat(const std::string& value) 
{
	float f;
	std::istringstream strin(value); /* error C2440: 'initializing' : cannot convert from 'std::string' to 'int' */
	strin >> f;
	if (!strin)
		return false;
	else 
		return true;
}
