log2(x) returns base 2 log logarithm of the elements of x, when x is a
REAL scalar, vector, matrix or array. The result has the same shape as
x.
If any element of x is MISSING, so is the corresponding element of
log2(x). If any element of x <= 0, the corresonding element of
log2(x) is MISSING. In both cases a warning message is printed.
When x is a structure, all of whose non-structure components are REAL,
log2(x) is a structure of the same shape and with the same component
names as x, with each non-structure component transformed by log2().
See topic 'transformations' for more information on log2().
