![]() ![]() The terms of service and privacy policy lack the clarity we’d like to see, though the app itself does not offer much more than an extended text note would in the way of features, save for automated temperature tracking. The Wand Blue is perfectly functional even if you don’t ever use the smart functions, though if you do use them, know that if you wish to store information-chiefly, temperature logs for multiple people-via the app, the company says: “ThermoWorks Apps do not collect any personally identifiable information, but in common with many commercial apps uses a third-party analytics service to collect anonymous usage information for the purpose of product improvement.” However, ThermoWorks does offer the option not to store data (this choice is embedded into the app sign-in). ![]() It’s the same contactless forehead thermometer but with the addition of smart capabilities, including wireless syncing with an app called ThermoWorks Health ( iOS, Android). If the ThermoWorks Wand No Touch Forehead Thermometer is your first choice but is unavailable, consider the company’s Wand Blue No Touch Bluetooth Forehead Thermometer. The American Academy of Pediatrics still recommends rectal thermometer use for newborns but acknowledges research that shows infrared thermometers are accurate for people over the age of 3 months. The UK now recommends that stick thermometers be used for armpit (axillary) measurements for newborns under 4 weeks and suggests using infrared forehead thermometers for any age above that. Although rectal temperatures have long been the gold standard for infants, many countries, including the UK, actively dissuade parents from using the oral or rectal methods at any age due to discomfort with the former and safety concerns with the latter (PDF). Oral thermometers today usually pull triple duty as armpit and rectal thermometers, as well. Using a stick thermometer orally is tough for most toddlers and preschoolers, so such models are recommended for people ages 4 and up. Three jumps get her closer than four, so $0.16$ rounded to the nearest $0.05$ is $0.15$.Digital stick thermometers are simple and offer reliable measurements and fast results, but you need to keep your mouth closed around the probe for anywhere between 10 and 60 seconds, and oral measurements may be skewed if you’ve recently consumed something very hot or cold. She wants to land as close as possible to $0.16$. A bug starts at $0$, and can only take jumps of $0.05$. ![]() Remark: One way to think of it concretely is like this. The second digit after the decimal point should be $5$ or $0$. And $1.87$ rounded to the nearest $0.05$ is $1.85$.Īlways, when we round to the nearest $0.05$, there should be at most two digits after the decimal point. Similarly, the number $1.88$, rounded to the nearest $0.05$, is $1.9$. When we are asked to round $0.16$ to the nearest $0.05$, what is meant is that we should find the number which is an integer times $0.05$, and is closest to $0.16$. One would often round to $0.14$, since $4$ is even.īut that doesn't seem to be what your question is about. ![]() A similar convention applies to say $0.145$ rounded to the nearest $0.01$, that is, to $2$ digits after the decimal point. That is often, but not always, resolved by rounding to the nearest even integer. For example, when we are asked to round $7.5$ to the nearest integer, there is a problem, since there are two nearest integers. ![]()
