There is a bug in puglin ROUND function:
The ROUND in plugin:
round: func [
[catch]
n [number! money! time!]
/even
/down
/half-down
/floor
/ceiling
/half-ceiling
/to
scale [number! money! time!]
/local m
][
throw-on-error [
scale: abs any [scale 1]
any [number? n scale: make n scale]
make scale either any [even half-ceiling] [
m: 0,.0 * scale + n
any [
all [
m = m: m - mod m scale
even
positive? m - n
m - mod m scale + scale
]
m
]
] [
any [
floor
ceiling
(ceiling: (found? half-down) xor negative? n down)
n: add n scale * pick [0,.0 0,.0] ceiling
]
either ceiling [n + mod negate n scale] [n - mod n scale]
]
]
]
ROUND in VIEW:
round: func [
{Returns the nearest integer. Halves round up (away from zero) by
default.}
[catch]
n [number! money! time!] "The value to round"
/even "Halves round toward even results"
/down {Round toward zero, ignoring discarded digits. (truncate)}
/half-down "Halves round toward zero"
/floor "Round in negative direction"
/ceiling "Round in positive direction"
/half-ceiling "Halves round in positive direction"
/to "Return the nearest multiple of the scale parameter"
scale [number! money! time!] "Must be a non-zero value"
/local m
][
throw-on-error [
scale: abs any [scale 1]
any [number? n scale: make n scale]
make scale either any [even half-ceiling] [
m: 0.5 * scale + n
any [
all [
m = m: m - mod m scale
even
positive? m - n
m - mod m scale + scale
]
m
]
] [
any [
floor
ceiling
(ceiling: (found? half-down) xor negative? n down)
n: add n scale * pick [-0.5 0.5] ceiling
]
either ceiling [n + mod negate n scale] [n - mod n scale]

Hi José,
JA> There is a bug in puglin ROUND function:
JA> m: 0,.0 * scale + n
...
JA> n: add n scale * pick [0,.0 0,.0] ceiling
Wow. Looks like somebody did a search and replace and messed it up.
Nice catch.

The thing is worst: even a rewrited ROUND function suffers this
find-and-replace
illness.

I discover the bug in decimal point values conversions in portuguese
Windows XP version. The problem occurs in any decimal value. If
Windows language is turned to US English, the problem does not occurs.

I guess if it occurs in european versions Windows. Seems a decimal
signal (comma) related problem.
