(Core :: JavaScript Engine, defect)

Description

[Norbert Lindenberg]

Intl.NumberFormat.prototype.format throws an error when asked to format a currency value with currencyDisplay="name":

typein:1:0 Error: internal error while computing Intl data

Calling unum_open with the style parameter set to UNUM_CURRENCY_ISO or UNUM_CURRENCY_PLURAL returns status U_UNSUPPORTED_ERROR.

In the API spec, both are listed as normal values of the parameter type UNumberFormatStyle, but then are not listed as possible values for unum_open. In the implementation, they are not supported in the big case statement in the implementation.

Adding the two constants to the switch statement seems to fix the problem.

In latest Firefox (33.0.2), I get the error for currencyDisplay = "name" as well as "code" (!).

Why isn't it fixed? Does Firefox use an old ICU version?

Comment 5

[Per Johansson]

Still same error as in the last comment in Firefox 37.0.1.

Comment 6

[ivar.is]

I am getting same error. 
1222221.0.toLocaleString("NL-en", {style: 'currency', currency: 'EUR', currencyDisplay: 'code', minimumFractionDigits:2, maximumFractionDigits:2})

When i used this funtion in my angular filter, its giving meta data like {{model.modelValue | CustomCurrency:model.currencyData}} in the html. only happens in firfox.

[Jeff Walden [:Waldo]]

If comment 6 still exists in a version of Firefox with this fixed -- that is, in Firefox 42 -- please file a new bug for it.  But currencyDisplay: "name" does generally work now.
