Function: write_binary_data (<X>, <D>) Writes the object <X>, comprising binary 8-byte IEEE 754 floating-point numbers, to the destination <D>. Other kinds of numbers are coerced to 8-byte floats.
write_binary_data cannot write non-numeric data.
The object <X> may be a list, a nested list, a matrix, or an array created by
make_array; <X> cannot be an undeclared array or any other type of object.
write_binary_data writes nested lists, matrices, and arrays in row-major order.
The destination <D> may be a file name or a stream. When the destination is a file name, the global variable
file_output_append governs whether the output file is appended or truncated. When the destination is a stream, no special action is taken by
write_binary_data after all the data are written; in particular, the stream remains open.
The byte order in elements of the destination is specified by
(%o1) true (%i2)
