It said it was round all about. I don't know. I suppose it could be.
As for rounding: 3.1 does not round to 4. 3.14 would round down to 3 not 4. I am kind of afraid of you being so much a science guy and all that and you think that the compass was around for thousands of years and that 3.1 would round up?
math = 4 and below rounds down. 5 and up rounds up.
So like if the measurement of something was 3.5 cubits it would round up to 4 cubits. But if the measurement of something was 3.1 cubits it would round down to 3 cubits.
Maybe God just but 3 because he figured an enlightened guy like yourself would have known that?
Fair?
