toFixed(2) rounds “x.525” inconsistently?

Question

I\'m experiencing rounding errors when using toFixed:

I used toFixed(2) on my numeric value calculations, but the rounding results are not as expected

Answer 1

Floating point inaccuracy means that most numbers ending .525 are actually .52500..1, and others are .5249999.....

Which way the value rounds depends on whether the closest actual representation in IEEE-754 floating point is above or below the desired value.
