Doubt regarding data type

how will we represent -1.23 what will be its datatype? float? but float does have signed and unsigned data modifiers

we represent them using float/ double. In float/ double we don’t have signed and unsigned data modifiers.

So which datatype is used?

float or double any can be used.

int main()
{
float t=-1.23
cout<<t;
}

output :
-1.23

You can verify above code.

if (still doubt )
