Follow-up Comment #21, bug #62417 (project octave):
re: comment 18:
works:
format short e
format shorte
format('short','e')
format('shorte')
errors:
format "short e"
format("short e")
all of which is fine, except this isn't a matter of combining different option
strings, as in 'copyfile a b'. we explicitly name the format option as 'short
e', with quotes in many places. e, E, g, and Eng are not independent options.
they only exist following long or short', and those are listed as different
specific option strings:
'long'
Fixed point format with 16 significant figures.
As with the 'short' format, Octave will switch to an
exponential 'e' format if it is unable to format a matrix
properly using the current format.
'short e'
'long e'
Exponential format. The number to be represented is split
between a mantissa and an exponent (power of 10). The
mantissa has 5 significant digits in the short format. In the
long format, double values are displayed with 16 significant
digits and single values are displayed with 8. For example,
with the 'short e' format, 'pi' is displayed as '3.1416e+00'.
'short g'
'long g'
Optimally choose between fixed point and exponential format
based on the magnitude of the number. For example, with the
'short g' format, 'pi .^ [2; 4; 8; 16; 32]' is displayed as
ans =
9.8696
97.409
9488.5
9.0032e+07
8.1058e+15
'short eng'
'long eng'
Identical to 'short e' or 'long e' but displays the value
using an engineering format, where the exponent is divisible
by 3. For example, with the 'short eng' format, '10 * pi' is
displayed as '31.416e+00'.
...
it would be like if in integral we described the option 'Waypoints' as 'Way
points', but didn't tell the user they can't call it as 'Way points'. I had
to look at the code to realize why the 'short eng' format can't be called as
'short eng'.
in m-code it would be simple to use a switch/case with case {'shorteng, 'short
eng'} to capture both, without any ambiguity in intent, and to match the
documentation as published. I still support either a doc change to clarify the
conflicting messaging, or doing the equivalent in the compiled function.
