floating-point format to store floating-point types has a problem with loss of precision. In C #, Java, provides the Decimal, BigDecimal encapsulation class to handle the corresponding, only to avoid the loss of precision.
Note: There are already decimal proposal in the ECMAScript specification, but it is not yet formally adopted.

Number.MAX_VALUE + 1 = numer.max_value;Number.MAX_VALUE + 2 = numer.max_value;...Number.MAX_VALUE + x = = Numer.max_value;Number.MAX_VALUE

In the past, when we redesigned a system, we always liked the big layout. Comprehensive system requirements, comprehensive analysis of system functions, and then comprehensively design the system, development, testing. Such a process often lasts months and takes a lot of work. However, not until the final design, no one knows whether there will be problems. This is the "big layout" of the ills.
Because of this, software gurus always emphasize that system refactoring should avoid

Divide a large file into several small file methods
For example, a BLM.txt file is divided into 1000 small files prefixed with blm_, and the suffix is a coefficient form, and the suffix is a 4-digit number form
First Use
Wc-l BLM.txt read out the BLM.txt file a total number of lines
and use the split command.
Split-l 2482. /blm/blm.txt-d-a 4 blm_
Divide fil
Because it involves reading data from large files, but the program memory is too small to read the reason, so the file is split to read
