Description popov895 2024-06-23 11:40:31 UTC 
SUMMARY

Since 24.05.0, there is an input field that contains an expression and an output field that contains the temporary result of calculating this expression. Pressing Enter or = moves the calculation result to the input field and clears the display field, but sometimes the display field doesn't clear. Actually, this is not a significant bug, but rather an inconsistent behavior.

STEPS TO REPRODUCE

1. Enter 55*2 - input field contains 55*2, display field contains 110
2. Press Enter - input field contains 110, display field is empty
3. Press cos - input field contains cos(110), display field contains -0,342020143326
4. Press Enter - both input field and display field contain -0,342020143326
5. Enter *2 - input field contains -0,342020143326*2, display field contains -0,684040286652
6. Press Enter - both input field and display field contain -0,684040286652
7. Further, for any operation, the display field is never cleared

Clear result display on single negative number

Display should clear when input is a single number, this covers the
case when the number is negative.
