QString::number(v, 'g', 3), how to change limits of 'g' for log. values

[HappyCoder]

Hi,

have values (v) from 2000 to 1E-10 and with that i got on a logarithmic axis

1000, 100, 10, 1, 0.1, 0.01, 0.001, 0.0001, 1E-05 ... and so on

How to modifiy it that values below 0.01 are in e-format

1000, 100, 10, 1, 0.1, 0.01, 1e-3, 1e-4, 1e-5 ...

Thx

Hi,

change the 'g' to 'e' or 'E' as you can see here.

You didn't understand it, that changes ALL values into e-format, not only some.
Nevermind, i found it by myself.

Well, good. Keep it a secret. After all, the purpose of this forum isn't really to share information, it's to get help for yourself only, right?

No panic, i had already written it here. Can i check it first if it realy works? Right?


The only solution i found was to check the value in a func an return it formated.

if( v >= 1E-1 )
            return QString::number(v, 'G', 3);
        else
            return QString::number(v, 'e', 0);

if( v >= 1E-1 )
            return QString::number(v, 'G', 3);
        else
            return QString::number(v, 'e', 0);
