Mathjs with number as Fraction and function equals

[maverick56]

I parameterize the mathjs like this :

const config: math.ConfigOptions = { number: "Fraction", }; const math: MathJsStatic = create(all, config);

I create units like this :

math.createUnit('rotation', {definition: '360 deg', aliases: ['tour','tr']})

I try to do this :
const a = math.unit(360, "deg"); const b = math.unit(1, "rotation"); expect(b.equals(a));

And i have this error :

TypeError: Cannot implicitly convert a number to a Fraction when there will be a loss of precision (value: 6.283185307179586). Use function fraction(x) to convert to Fraction.

Any idee ??!
tks.

Apparently the method Unit.equals internally tries to convert the Fraction into a number. For some reason the function math.equal(a, b) does work as expected whereas b.equals(a) throws this error.

I'll turn this discussion into an issue.

It sounds like this is a solvable bug. Anyone able to look into this? Help would be welcome.
