|
|
|
|
## [0.2.0] - 2023-04-15
|
|
- use new weight factor 201.3868 to reduce maximum relative error
|
|
- create **elements_uint16.h** file.
|
|
- move **ATOMIC_WEIGHT_FACTOR** to **elements_uint16.h** file.
|
|
- create **elements_name.h** file with full element names. Uses ~1670 bytes of RAM.
|
|
so will **NOT** work on all boards.
|
|
- add related constants
|
|
- **AVOGADRO** = 6.02214076e+23; number of particles in one mole.
|
|
- **DALTON** = 1.66053907e-24; weight of one nucleon in grams.
|
|
- **ELEKTRON_VOLT_JOULE** = 1.602176565e-19; eV in Joule
|
|
- **ELEKTRON_VOLT_GRAM** = 1.7826619e-39; eV in grams
|
|
- **DALTON_EV** = 931.4940954e12 = DALTON / ELEKTRON_VOLT_GRAM
|
|
- **DALTON_JOULE** = 1.036427015e5 = DALTON / ELEKTRON_VOLT_JOULE
|
|
- update unit tests.
|
|
- update readme.md
|
|
- update keywords.txt.
