Answer 2

Normal javascript numbers are very accurate and float32 arrays have less accuracy then normal js numbers. The point of typed arrays is for efficiency not accuracy.

Answer 3

Zachiah sawyer floating numbers in js behave like this:0.1+0.2=0.30000000000000004;
we can use toFixed method to fix them. but when I assign it to float32, lose accuracy. why?
