Cannot handle pixel values >~3e38 (v3.0.0-beta.2b)

[astrojysun]

When opening an image with very larger values (>~1e38), all pixels with values larger than ~3e38 are displayed as Inf. The screenshot below demonstrates this issue: all the black pixels show up as Inf in the GUI, but they really aren't.

Platform info:

• Backend OS: CentOS 7
• Frontend Browser: Chrome
• CARTA Version: v3.0.0-beta.2b

Is this an image with BITPIX=-64 ?

[astrojysun]

Yes, it is.

@astrojysun thank you for reporting this. With some internal discussions, we think we know the reason. Will schedule a fix.

do you think you can take log10 or apply a constant shift in unit?
