Different orders of magnitude aren't a problem when multiplying floats, because the order-of-magnitude portion gets translated into addition of exponents.
They're a problem with fixed point: might you have been thinking of that?
- Dylan16807 1y agoWe're not looking at instructions in a vacuum. No matter what you have both multiplications and additions happening. So they're making a point that if you apply more multiplications before the inevitable addition, you are likely increasing the danger levels of that addition.
- wizzwizz4 1y agoOh, if one of the multiplications yields a positive number, and another yields a negative number of similar magnitude? That makes sense; I forgot linear spaces were over fields.
