Android Question B4X Why this error?

Mauricio Pereira · Jun 16, 2020

The following error appears in the simple attached program:
Error occurred on line: 39 (Main)
java.lang.NumberFormatException: Invalid double: "2,000.88"
at java.lang.StringToReal.invalidReal(StringToReal.java:63)
at java.lang.StringToReal.initialParse(StringToReal.java:164)
at java.lang.StringToReal.parseDouble(StringToReal.java:282)
......
Why ??

From the error it probably doesn't like the comma thousands separator.

You are using a Formatted Double (x) to check if the value is greater than 999. Do such tests on the Double.

B4X:

If A > 999 Then
        Log(X)
    Else
        Log(X)   
    End If

B4X:

X = formatter.Format(A)

DonManfred,
The problem is with the formatter...
If we use X = NumberFormat2 (A, 1,2,0, False) it works!

As DonManfred said. Test the Double value directly - don't format it into a String.
