[Octave-bug-tracker] [bug #59719] dec2bin issues an error for non-integer inputs while Matlab does not

[Nicholas Jankowski]

Follow-up Comment #2, bug #59719 (project octave):

just for compatibility reference, the Matlab public facing help does
explicitly say that:


D — Input array
numeric array
Input array, specified as a numeric array.

If D is an array of floating-point numbers, and any element of D has a
fractional part, then dec2bin truncates it before conversion. For example,
dec2bin converts both 12 and 12.5 to '1100'. The truncation is always to the
nearest integer less than or equal to that element.

If D is a character or logical array, then dec2bin treats the elements of D as
integers. However, dec2bin treats characters as their Unicode® values, so
specifying D as a character array is not recommended.

Since R2020a

D can include negative numbers. The function converts negative numbers using
their two's complement binary values.
