For working with money, toFixed 2 is perfect. I leave that as an exercise for the reader. 095 fails for 1, then 4 through 7, then 16 through 128 Those of you with more binary and floating-point math knowledge than me can probably reason out the underlying cause. fixing numbers ending with. toFixed 6 ;. I had missed it until December 2017, and that spurred me to check for other problems. 025 fails 1, 2, 3, then 16 through 63• fixing numbers ending with. This article was originally published on.

That leaves the programmers to focus on the small without seeing a larger pattern. The fixed number of digits argument to toFixed is calculated from the length of the fraction value. 015 fails for 1, then 4 through 7, then 128•。 。 。
