X^Y on the Elektronika B3-19M

[watchmaker]

The result of "x^y" differs slightly from the result of "ln"+"*"+"e^x" (unlike B3-21, B3-34!). E. g., 8 | 8 x^y gives 16777188, 8 | 8 ln * e^x gives 16777173. But the same operation with DECIMAL logarithms (8 | 8 lg * | 10 ln * e^x) gives 16777188. Most probably it uses a similar algorithm, directly placing ln(10) in Z.
