In general, then, a later test for a set invalid flag is needed to detect all cases where NaNs are introduced [ 3 ] (see Function definition below for ...
In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.
