Locale: calling formatNumber with maximumfraction 15 and rounding returns strange number

[Sovia]

Describe the bug
Calling formatNumber with a maxiumFraction/minimumFraction of 15 and round: true is returning an incorrect value.

To Reproduce

Steps to reproduce the behavior:

1. Copy test-format-number-15-decimal.zip into the codebase
2. Navigate to /components/locale/test-format-number-15-decimal.html
3. Enter the value "123.54"
4. See error

Expected behavior
The value in after calling formatNumber should be "123.540000000000000", not "123.540000000000006"

This issue happens starting with 14 fraction digits

[vonnyw]

Actually it happens on numbers with high number of precision not starting with 14. It starts breaking when entering more digit before the decimal. The attached shows the maximum digit can be entered without rounding error.

Putting this note on:

10 digits precision, the maximum digits before the decimal is 7, 
11 digits precision, the maximum digits before the decimal is 5,
12 digits precision, the maximum digits before the decimal is 4,
13 digits precision, the maximum digits before the decimal is 3,
14 digits precision, the maximum digits before the decimal is 2,
15 digits precision, the maximum digits before the decimal is 1,

Whats the priority here?

Need one more fix which is not working

31.15

• 16 digits on left, 77 decimal should not round to 80
  1234567890123456.77 -> 1234567890123456.770000000000000

Putting this on hold for now as i found it is working.

• https://4523-enterprise.demo.design.infor.com/components/locale/test-format-big-negative.html
• paste this in the console

Soho.Locale.formatNumber('1234567890123456.77', { decimal: '.', group: '', maximumFractionDigits: 15, minimumFractionDigits: 15, round: false, style: 'decimal'})

So it will work if its a string since its a large number we need to do this. Because if you just paste 1234567890123456.77 JS will immediately round it as the number is too big for it.

Two more test cases

• go to https://main-enterprise.demo.design.infor.com/components/dropdown/example-validation.html?locale=el-GR (or any page in greek) and paste in the console
• Case 1

Soho.Locale.formatNumber("1234567890123456.77000000000000000", {style: 'decimal', round: true, minimumFractionDigits: 15, maximumFractionDigits: 15})

Get: '1.234.567.890.NaN.000.000.000.000.000'
Expect: '1.234.567.890.123.456,770000000000000'

• Case 2

Soho.Locale.formatNumber('1234567890123456.77', { decimal: '.', group: '', maximumFractionDigits: 15, minimumFractionDigits: 15, round: false, style: 'decimal'})

Get: "123456789012345677.000000000000000"
Expect: "1234567890123456.77000000000000000"

Basically it's any locale that use a comma ',' for a decimal separator and a period '.' for a group separator.

There are numerous locales that have that (about 20 in all).
da-DK, da-DE, el-GR, es-AR, es-ES, etc...

QA Passed. Working as expected on my end.
