the part of the effective digit is always 1.xxxxxxx ... (23 x). Another area to be aware of is the exponential representation, which is stated in the IEEE754 by means of an offset exponent, meaning that the number in the digits minus 127 is the final exponent. Compare the exponent portion of the above figure to 01111100 and convert it to a decimal number of 124. Then subtract 127, the result is-3, which means that the exponent part is 2-3=1/8=0.125. What about the number of effective parts? Plu

dual-tube telescope is suitable for daytime views, but it is not suitable for astronomical purposes because it cannot gather enough light. How can we know the diameter of the dual-tube telescope? Very simple.Each pair of dual telescope is labeled with a set of numbers such as 7x50. The first digit "7" on the dual telescope specification is the "magnification", and the second digit "50" is the diameter of the lens.

In lowercase, x indicates that a character is deleted backward, that is, the character where the cursor is located is deleted.
Nx n indicates a number, indicating that each character is deleted backward. For example, 10x indicates that the last 10 characters including the cursor are deleted.
X in uppercase indicates that a character before the cursor is deleted, excluding the character where the c

-126) from overflow (this is hard to understand, as mentioned in the document ). here, 127 and-126 are represented as the index of 2. what is the value when the index is expressed as 10? We know that the inverse function of function y = 10x is x = log10y. of course, here 10 can be any other number. therefore, 2127 = 10x => x = log2 (127) = 38.23 is approximately 38, and log2 (-126) =-37.99 is approximately-

This article mainly introduces how to significantly improve the full table scan speed of InnoDB in MySQL. The author talked about pre-reading and multiple asyncIO requests to reduce the impact of InnoDB on MySQL speed, for more information, see
Faster full table scan in InnoDBGenerally, most applications use indexes to query a few rows of data (primary key query or intra-hundred rows query), but sometimes we need to query the entire table. Typical full-table scans are logical backup (mysqldump)
case we're re getting 4.5x of throughput compared to single thread and 100% utilization. we're re also getting almost double throughput of the run with 4 thread where 100% utilization was reported. this makes sense-there are 4 drives which can work in parallel and with outgoing outstanding requests they are able to optimize their seeks better hence giving a bit more than 4x.
So what have we so? The system which was 96% capacity but which cocould have driven still to provide 4.5x throughput-so i

Advantage: the parsing speed is fast, and the memory usage is not related to the XML size (the XML memory usage increases without increasing ).
Disadvantage: poor usability because there is no structure information and it cannot be traversed. XPath is not supported. If the structure is needed, you can only read and construct a little bit, which is especially difficult to
