Earlier I have talked (and held a vote) about extended format strings,
but as reminder, for a while in 2.3.24 nightly you can do things like
this:
${n?string("#.00;; rnd=hu inf='∞'")}
or set the number_format setting to something like that. The thing to
note is the section after the 2nd ";", which is not allowed be
DecimalFormat (as it only supports two sections), it's an extension by
FreeMarker.
How should the option names look? Like instead of the current
abbreviated form, it could be like "#.00;; rounding='half-up'
infinity='∞'" too. Currently it's like below. Opinions?
rnd
Rounding mode. The value is one of u for up, d for down, c for
ceiling, f for floor, hu for half-up, hd for half-down, he for
half-even, and un for unused. (See the java.math.RoundingMode API
for explanations.)
mul
Multiplier. The number will be shown after multiplied with this
integer number.
dec
Decimal separator character (like "." in 3.14).
mdec
Monetary decimal separator character. This is used instead of dec
when the pattern contains parts that make it a monetary format. (See
the Java decimal number format documentation for more.)
grp
Grouping separator character. Note that grouping is turned on by
using "," in the patter, as shown in the earlier example. If it's
not turned on, this option won't have visible effect.
exp
Exponent separator string. Only has visible effect if the pattern
specifies exponential form, like "0.##E0".
min
Minus sign character.
inf
The string used to show infinity.
nan
The string used to show not-a-number (NaN).
prc
Percent character.
prm
Per-mill character.
zero
Zero character. This modifies the other digits too, for example, if
zero is A, then 1 will B, 2 will be C, and so on.
curc
Currency ISO 4217 code. Only has effect when the pattern contains
parts that make it a monetary format. It's an error to specify a
code that's not a known ISO 4217 code in the Java installation.
curs
Currency symbol; shown where the localized currency name is present
in the pattern. Overrides the symbol determined from curc.
