Reason: JS in accordance with the 2 to deal with decimal subtraction, on the basis of arg1 arg2 precision extension or reverse expansion matching, so will appear as follows. JavaScript (JS) decimal point subtraction problem, is a JS bug such as 0.3*1 = 0.2999999999, the following list can be perfect to find the corresponding accuracy of the four JS algorithm function Accdiv (arg1,arg2) {var t1=0,t2=0,r1,r2; Try{t1=arg1.tostring ().

And when multiple users access the distributed application at the same time, the data from different users will be automatically separated and routed to the corresponding oscilloscope and finally c

We all know that the high flow of the site means that the source of money, can be converted into money in a variety of ways, only you have the flow, but not everyone can do this, but also not all the sites are pursuing this point. This is true for the educational products we operate, because our audience is that potential buyers are specific groups, so we do not pursue through high flow to make the flow of money, but the promotion to do fine, do not seek high flow, only the flow of

Pdop: Position dilution of precision. It is translated as "precision intensity" and is usually translated as "relative error ". The specific meaning is: because the quality of the observed results is related to the geometric shape between the measured man-made satellite and the receiver, therefore, calculating the error volume caused by the above is called the strength of accuracy. The better the satellite

1. ScopeThe float and double ranges are determined by the number of digits of the index.The float index has eight digits, while the double index has 11 digits. The distribution is as follows:Float:1bit (symbol bit) 8 bits (index bit) 23 bits (tail bit)Double:1bit (symbol bit) 11 bits (index bit) 52 bits (tail bit)Therefore, the float index range is-127 ~ + 128, while the double index range is-1023 ~ + 1024, and the index bit is divided by complement code.The negative index determines the smalles

Phpround problems (incorrect precision results) php It is found that there is a problem when using the PHP round function for decimal control, as shown below: Expected value of round (9999999999999.99, 2): 9999999999999.99; actual value: 10000000000000 Expected value of round (1111111111111.11, 2): 1111111111111.11; actual value: 1111111111111.1 Have you encountered any similar problems?

Sartorius electronic balances are precision, general purpose products that typically use an electromagnetic force sensor ( See load cell )to form a closed-loop, self-regulating system with good stability and high accuracy. It is a comprehensive product of sensor technology, analog electronic technology, digital electronic technology and microprocessor technology, and has many functions such as automatic calibration, automatic display, overload protect

Most programming languages have several numeric data types, but JavaScript has only one. You can use the TypeOf operator to see the type of numbers. Whether it's an integer or a floating-point number, JavaScript simply categorizes them as numbers. typeof 17; Number typeof 98.6;//number typeof-21.3;//number In fact, all the digits in JavaScript are double-precision floating-point numbers. This is a 64-digit coded number--"doubles"--develo

BC is the abbreviation of binary calculator. The arguments for the bc* function are the operands plus an optional [int scale], such as String Bcadd (String $left _operand, String $right _operand[, int $scale]), if scale does not provide , the default value of Bcscale is used. The large number is directly represented by a string of 0-9, and the result returns a string. Bcadd-adds two high precision numbersbccomp-compares two high-

This article explains why the range of float is larger than int (same as 4 bytes), but some int is not correctly expressed by float (loss of precision)The precision problem of float and double in Java1. Background KnowledgeIn Java there is no detail, just said float accounted for 32 bits (bit), double accounted for 64 bits.For a computer, it is appropriate to use a number of digits. But someone likes to use

Typically, a float or double is used to calculate the currency.What does the following calculation output?System.out.println (2.00-1.10);Started thinking it would be 0.90, the actual result is: 0.8999999999999999The reason is that not all decimals can be accurately represented by binary floating point.How to transform it? Use int, long to calculate, and then convert to floating point number. Use BigDecimal to calculate. System.out.println (New BigDecimal ("2.00"). Subtract (New BigDec
