Not sure if this is the right place to ask. I’m working on a material that involves a very small number in the math node; Plank constant, Boltzmann constant. in which Blender always round those numbers to 0 (floats precision maybe). I have proved it using this:

The top one is Plank constant and the bottom one is Boltzmann constant, which is clearly TWO different numbers. But when using a Compare node, Blender outputted 1, which means is see both of this as the same value. Also, I could not increase both of these two values using a Multiply node. So, I conclude Blender rounded it up to 0.

I didn’t input those minuscule numbers on the field itself but the number became absurdly small in calculation; Plank constant inputted as

instead of “6.6260702e-34” on the field. Which, before you ask, the second method didn’t work too.

So, Is there any way to increase Blender’s precition. Script? Add-on? or something I might not have known before. Thank you in advance!
