Return a matrix or N-dimensional array whose elements are all eps, the machine precision. More precisely, eps is the largest relative spacing between any two adjacent numbers in the machine's floating point system. This number is obviously system-dependent. On machines that support 64 bit IEEE floating point arithmetic, eps is approximately for double precision and for single precision. Given a single argument x, return the distance between x and the next largest value.
