Negative sign is highlighted as operator but should be part of the number

Have the following code:

double foo()
double foo()
{
    int i = -1234;
    float f = -1234.f;
    double d = -1234.0;
    double e = -1234.0E5;
    return i + f + d + e;
} 

and note that the minus-signs are highlighted like operators.

In my opinion, they belong to the number (like the `.f` or `.0`, or `.0E5`, which are all highlighted as part of the number).

I'm aware that the compiler also treats `- 1234` as valid negative sign, but in this case I would leave the highlighting as is (I also think it is bad style to write numbers like that).
