		Title: "Go constants cannot express negative zero",
		Text: `In IEEE 754 floating point math, zero has a sign and can be positive
or negative. This can be useful in certain numerical code.

Go constants, however, cannot express negative zero. This means that
the literals \'-0.0\' and \'0.0\' have the same ideal value (zero) and
will both represent positive zero at runtime.

To explicitly and reliably create a negative zero, you can use the
\'math.Copysign\' function: \'math.Copysign(0, -1)\'.`,
