I'm not sure if r in n = r * balance or in d = 1 - (1 + r)**(-term),
is the same as rate given in the definitions.

Same uncertainty with principaland princ,
and with n and int.

yes

isnt it because you use Math.round() instead of Math.floor() for the mantissa ?

reference solution sometimes gives incorrect result:

input : 107.88354150716061: expected '010000101101011111000100011' to equal '010000101101011111000100010'
input : 925.3339639566982: expected '010001000110011101010101011' to equal '010001000110011101010101010'

I think random number should be rounded to 6 or 7 digits first. Reference solution could be build on DataView or on other solution.

Thanks :)

added random tests

can you update it to 3.0?

As I did :(

Looks like you've solved it

Thank you. It's working now

You mean the argument? Some languages do not allow uppercase letters for variable names. In JS, N seems to be applicable; in other languages, n might be applicable.

Just read over it. CodeWars supports multiple languages, and sometimes this stuff happens.

If it offends you that references to other languages seep through in JS descriptions, do a couple of Haskell kata. Concepts that are different are quite often left untranslated.
