binary

Function: binary
Section: conversions
C-Name: binaire
Prototype: G
Help: binary(x): gives the vector formed by the binary digits of x (x
 integer).
Doc: outputs the vector of the binary digits of $|x|$. Here $x$ can be an
 integer, a real number (in which case the result has two components, one for
 the integer part, one for the fractional part) or a vector/matrix.
 \bprog
 ? binary(10)
 %1 = [1, 0, 1, 0]

 ? binary(3.14)
 %2 = [[1, 1], [0, 0, 1, 0, 0, 0, [...]]

 ? binary([1,2])
 %3 = [[1], [1, 0]]
 @eprog\noindent For integer $x\ge1$, the number of bits is
 $\kbd{logint}(x,2) + 1$. By convention, $0$ has no digits:
 \bprog
 ? binary(0)
 %4 = []
