Measure Lux values under 1

Hi folks,

Could not find the easy answer anywhere from the net.

In my project, i would like to measure values (also) between 0 - 1.
Is that possible with BH1750?
Haven't checked if the function I use, does the rounding, therefore I could change the code.
I was thinking to ask here if someone has straight answer.

-Thanks and Cheers

Read this. Not with this one...

EDIT : TSL2561 will go down to 0.1lx if it is enough...
