I get the following when using ⍕:
12 ¯4 ⍕ 9.9994 9.9995 9.9996 ¯9.9995E¯10 ¯9.9996E¯10
9.999E0 9.999E0 0.000E0 ¯0.000E¯10 ¯0.000E¯10
This should display as:
9.999E0 1.000E1 1.000E1 ¯1.000E¯9 ¯1.000E¯9
The error in (12 ¯4 ⍕ 9.9996 ¯9.9995E¯10 ¯9.9996E¯10) seems to be
related to the failure to increase the exponent by 1 and reduce the
coefficient by 9 when the coefficient rounds to 10.000
The error in (12 ¯4 ⍕ 9.9995) is probably related to ⎕CT and
binary/decimal conversions and may not be considered a true error.
