Description Michael Tsang 2020-04-07 01:31:22 UTC 
SUMMARY

The calculator messes up with the precedence with unary operators in scientific mode.

Assume that I want to calculate 1/(1/12+1/6). The expected result is 4.

STEPS TO REPRODUCE
Click the buttons below in sequence
( 1 2 1/x + 6 1/x ) 1/x

OBSERVED RESULT
The screen displays 0 after +, 0.166666666667 after ), and 6 after the final 1/x


EXPECTED RESULT
The screen displays 0.0833333333333 after +, 0.25 after ), and 4 after the final 1/x
