rounding error

(redirected from rounding errors)

rounding error

1. The difference between an exact mathematical value and the value that is approximated during a calculation or computation in which rounding occurs. So many of the values we have to use in these calculations have decimals that extend to an infinite length that rounding errors are simply unavoidable. It may seem like we leave a very large rounding error when we use 3.14159 as the value for pi, but in most instances it will give us a result that it accurate enough for our purposes.
2. A figure that is or seems large in isolation but is relatively small or immaterial to a large company. The settlement of $300,000 is little more than a rounding error to a global corporation that earns billions of dollars each year. I'm nervous about asking for a raise, but I'm trying to tell myself that it is just a rounding error in the company's eyes.

rounding error

a large amount of money that is relatively small in comparison to a much larger sum. To a large company like Smith & Co., a few thousand dollars is just a rounding error. It's not a lot at all.

Noting that Neon Therapeutics is now trading with a market cap below $100M, Mizuho analyst Salim Syed said the selloff in the stock following the company's NEO-PV-01 data "seems to be more related to a financing overhang than the actual data itself or any fundamentals." He thinks a business development deal scenario "is actually not that far-fetched" and could be an underappreciated near-term catalyst, arguing that "all it takes is one BD deal to move the stock considerably higher from these trading levels." A larger pharma company could have a lot of option value getting involved at this point, said Syed, who contends that "upfront payments are often 'rounding errors' for large-cap companies." He keeps a Buy rating and $21 price target on Neon shares.
In the context of space launch, where $35 billion megaprojects are more common, the sums being spent in support of the Cornwall spaceport project hardly even rise to the level of rounding errors. And that just illustrates how incredibly cheap it might be for Virgin Galactic and Virgin Orbit to expand their businesses and challenge other companies with more "traditional" plans for launching rockets (i.e., vertically, from launchpads).

He said the growth upgrades "amounted to little more than rounding errors" and said the PS27bn public finance boost over the next five years was "small beer" on an annual basis.
To improve positioning accuracy, the proposed method focuses on the following three issues: (a) determining a more accurate reference point, (b) reducing rounding errors using a coordinate translation process, and (c) estimating direction averaging and speed averaging of waypoints.
