Setting the max precision ( tried from 5 decimal zeros to max)

Dimension Precision (6 decimals)

click on horizontal line, enter length 43.34375 ( I have tried using math ie. 86.6875/2 for the length too)
I set the snap point to end after I took the image shots. snap point has no affect.

hit enter or move mouse over the drawing

Resulting line and Dimension display.

Did I miss something?
