B4J Question error with small numbers using b4xeval

[jjarrell]

When the numbers are smaller than 3 decimal places in parenthesis b4xeval appears to treat it as a string instead of a number causing it to error.

Any ideas?

    Dim e As B4XEval
    e.Initialize(Me, "Eval")

    Log((.03+.02)/2)
    Log(e.Eval("(.03+.02)/2"))
    
    Log((.003+.002)/2)
    Log(e.Eval("(.003+.002)/2"))
    
    Log((.0003+.0002)/2)
    Log(e.Eval("(.0003+.0002)/2"))

Results in log:

0.025
0.025
0.0025
0.0025
2.5E-4

Change line 60 in the class to:

    sb.Append(NumberFormat2(d, 1, 15, 0, False))

Thanks. That worked.
