Floating point math problems

[inick]

I've played enough sandbox to identify a couple times when 100 does not equal 100. Where 100 turns to 99.9 and you cannot obtain the last 1% I'm almost convinced it's due to rounding issues. I'm going to take fluid in pipes as my first example. The offshore pump doesn't push 999.9/s. Oil refineries don't produce 44.9 Petroleum Gas. Lubricant doesn't produce 19.9. But, as soon as any fluid enters a pipe, 0.1 fluid is lost and can't be made up. Perfect building to building connection (boiler -> steam engine -> steam engine) won't lose any of the fluid. Pipes shouldn't have a floating point for it's volume. Tanks shouldn't either. Make it a whole integer. The only thing that outputs floating points that I can recall are pumpjacks for crude oil. So, change it to a fixed INT (FLOOR() it's value: 16.8 = 16, 16.1 = 16, 0.9 = 0).

Second issue - also think it's related to floating points but not sure. Reproducable. Any science pack (let's start with just red Automation) while being consumed in a lab when power browns out (yellow or red energy bar), but not a blackout (zero energy). will consume 1% of the science pack so the research tech you've made 10 packs for 10 required will take 11 packs to complete with 99% left over of #11.


Yea, I'm nitpicking details. I want my 1%!
TY for reading. Hope to see this addressed.

Maybe fluids should not behave like solids? There may be an unusable puddle left in the pipe.
And what about gases? Can you squeeze a pipe till the vacuum?

Systems that have a possibility of not being full at all times in all places; behave in this way. You may be falling prey to the Observer effect. Fluid actively moving in and out of a pipe will never make it full. To fill a pipe section (or tank or whatever fluid thingy) completely, attach a pump into it leaving the other end disconnected.

And as long as we're nitpicking, 1% of 100 is 1.

Aye. Floating point math has been troublesome for me, and add percentages in floating point math and I need more than the few moments I took to write it to be possibly right. Still has a chance to be wrong.

You are correct. I am wrong of 1% of 100 is not 0.1
High school was so long ago. It's been... 84 year..no. It's approaching 30 though.
