Steps to reproduce

Open the PowerToys Run prompt and perform a subtraction with the first number being a float.

Not sure how exactly to word when it occurs, but it seems to occur when the result is randomly between 10^1 or 10^2 smaller than the original.

Example 1: =1189390.24-1183760.67

Example 2: =123456789.01-123456789.00

Example 3: =100000.01-90000

Example 4: =100000.01-90001

Example 5: =1000.01-990

Example 6: =1000.01-991

✔️ Expected Behavior

Example 1: =1189390.24-1183760.67 should return 5629.57
Example 2: =123456789.01-123456789.00 should return 0.01
Example 3: =100000.01-90000 should return 10000.01
Example 4: =100000.01-90001 should return 9999.01
Example 5: =1000.01-990 should return 10.01
Example 6: =1000.01-991 should return 9.01
