Invalid type passed to bignum constructor

[VirtuousDeath]

hi,
I am experiencing this issue with your bignum package.

I have downloaded the types for bignum and it forces me to create an instance of
the default export.

What am I doing wrong?
here is some of the code I made for this issue to happen,
strangely it worked sometime ago

...
this.value = new bignum(value, base).abs().toString()
...

I wish you can help,
thanks

May sound stupid, but can we actually convert bases with this version of bignum?
As Example:

this.value = bignum(value, base)

Could be a good implementation, and set default base to 10.
Anyways, I wish to check that, If it doesnt have I need to know

Realised that bignum doesnt have support for decimal numbers
