Thus under some conditions, the major portion of the significant data digits may lie beyond the capacity of the registers. Therefore, the result obtained may have little meaning if not totally erroneous. The Z1, developed by Konrad Zuse in 1936, was the first computer with floating-point arithmetic and
Some servers can log information to computer readable formats (such as JSON) versus the human readable standard. [17] More recent entries are typically appended to the end of the file. Information about the request, including client IP address , request date / time , page requested, HTTP code, bytes served, user agent , and referrer are ...
However, log-space reductions are probably weaker than polynomial-time reductions; while any non-empty, non-full language in P is polynomial-time reducible to any other non-empty, non-full language in P, a log-space reduction from an NL-complete language to a language in L, both of which would be languages in P, would imply the unlikely L = NL.
L is a subclass of NL, which is the class of languages decidable in logarithmic space on a nondeterministic Turing machine.A problem in NL may be transformed into a problem of reachability in a directed graph representing states and state transitions of the nondeterministic machine, and the logarithmic space bound implies that this graph has a polynomial number of vertices and edges, from ...
A language is said to be log-space reducible to a language if there exists a log-space computable function that will convert an input from problem into an input to problem in such a way that (). This seems like a rather convoluted idea, but it has two useful properties that are desirable for a reduction:

In computational complexity theory, a log-space computable function is a function : that requires only () memory to be computed (this restriction does not apply to the size of the output). The computation is generally done by means of a log-space transducer .
Three formats are especially widely used in computer hardware and languages: [citation needed] Single precision (binary32), usually used to represent the "float" type in the C language family. This is a binary format that occupies 32 bits (4 bytes) and its significand has a precision of 24 bits (about 7 decimal digits).
