2012年2月28日 · Does .NET have a built-in method to calculate the ULP of a given double or float? If not, what is the most efficient way to do so?

2021年3月15日 · From ULP Wikipedia's page: Another definition, suggested by John Harrison, is slightly different: ULP(x) is the distance between the two closest straddling floating-point numbers a and b (i.e., th...

2017年5月14日 · For example, if f is restricted to six binary digits, then it has values from 1.00000 to 1.11111, and the smallest change that can be made in it is 0.00001. Given the exponent e, a change of 0.00001 in f modifies the value represented by 0.00001•2 e. This is the unit of least precision (ULP) Note that the ULP varies depending on the exponent.

2020年4月28日 · Code on the ULP continues to execute when the board wakes up and goes to normal power mode. So when it is awake, it will still run the counter on the ULP processor unless you stop the ULP periodic wake up timer, ULP will keep waking up …

2014年7月9日 · I need the ulp for a given double value, but since I am developing for Codename ONE, ulp (double) is not provided. Does anyone know an efficient algorithm to compute ulp in Java? Codename ONE provides

2020年6月29日 · I have encountered the following definition of the Ulp (from this article1, Definition 5.): Despite something left unclear (does the word linearly in the definition mean that between two FP (float...

2019年1月31日 · For a number x in the binary floating point number system, units in the last place is defined as ulp(x) = 2^{E(x)} * 2^{1 - p} = 2^{E(x)}*epsilon, where the exponent is the exponent of the base 2 used to represent x, p is the precision of the number format (53 for the double precision format), and epsilon = 2^{1-p} is the machine tolerance.

2022年4月24日 · I am going to continously measure ADC data with ULP. Periodically I wake up ESP32 to do some stuff. When I analyse data received from ADC I found that there is about 100 ms of time where ADC return...

2022年6月28日 · This will still let me use the ULP to do a more complicated wake-up. What I'm really looking for is to wake up on a GPIO pin transition, after a suitable software debounce time, or after a certain amount of time has elapsed.

2021年3月12日 · My application should initialize the ULP coprocessor and the coprocessor should observe one GPIO. The ULP Timer should wake up the coprocessor in certain intervals and then the coprocessor should c...
