Sometimes we have a royalty formula for each product, and the formula used for this calculation exists in the table in the string format. when we use this formula, it is not like the one we wrote: $ a2 + 3*5; in this way, the result can be calculated simply, and it is a string. therefore, we must convert the string int

Today, a user wrote an email to me about the formula in the list calculation column when reading the SharePoint Portal Server 2003 deep guide, the book only states that "the calculated value formula also supports many functions. Readers can refer to the SharePoint help documentation for a deeper understanding." So the netizen asked me which functions can be used

Polygon Area Calculation Formula Function polygonArea (points) {var I, j; var area = 0; for (I = 0; I Polygon Area Formula description: We all know the three-point area formula of A (x1, y1), B (x2, y2), and C (x3, y3). | x1 x2 x3 |:S (A, B, C) = | y1 y2 y3 | * 0.5 = [(x1-x3) * (y2-y3)-(x2-x3) * (y1-y3)] * 0.5 P

There are 33pf filtering capacitors in the audio line, mainly filtering out MHz RF interference. How can this problem be calculated,Is the 217hz tdd_noise related to the filter capacitor? Or should I filter out series inductor or magnetic beads? 2 * pI * freq = SQRT (1/(L * C ))That is to say, This capacitive resonance point has the smallest impedance.You can check the encapsulation parameters of the resistance and capacitance of Murata.Generally, about 0402 of the encapsulation is about 0.5nh

The chief executive sent an e-mail. Request the BOM to increase the "unit price" and "Total Price". "Unit Price" is filled out by its approval, "Total price" is calculated according to "Unit price" and "quantity". and increase the "total amount", the value is equal to the sum of the total price in the schedule.Sub-tabular format required by the Executive DirectorXiaoming quickly changed the data model, form, and data permissions, and then found that the fluffy asked how to proceed with the autom

quantities are shown on the graph. Then from \ (oz=1\) Start step by step to the length of the line (ZZ ' \) and \ (Z ' t_1\), and then calculate the \ (\tan{q} \), you can get the formula above. This process has been written in the picture, no longer repeat it.When the celestial body rises/falls, (great circle) arc \ (ZB = {90}^{\CIRC} \), spherical triangle \ (zbp\) Three sides are known, directly apply the cosine theorem:\ (\cos{zp} = \cos{bz}\cos

where P is full, r is monthly, and N is the number of periods.For equal principal and interest, the repayment amount of each month is the same, but the interests are decreasing, the first month is the full one-month interest, the second month is to remove the first month after the principal amount of the remaining one months interest, as follows:Assuming a monthly repayment of X, full m, monthly RA1 = X-m*rA2 = x-(M-A1) *RA3 = x-(M-A1-A2) *r...an = X-(M-A1-...-an-1) *ran+1 = x (because A1 + ...

,The total monthly supply remains unchanged. Equal principal method The largest feature of the same amount of principal method is that the monthly repayment amount is different and shows a decreasing status month by month. It distributes the loan principal equally by the total number of months of repayment, plus the interest of the remaining principal in the previous period, in this way, the monthly repayment amount is formed. Therefore, the amount of the first month of the same amount of

In C #, convert the string to the calculation formula and calculate the result, According to the summary, there are three types: First, use the Compute method in the DataTable. Example: "1*2*3" The Code is as follows: Var a = new System. Data. able (). Compute ("1*2*3", ""); // result a => 6 Method 2: parse using Eval method in javascript. This method requires adding COM reference: Microsoft Sctipt Control

BackgroundUsers often need a certain number of words to fill in the required field restrictions, but JS is taken out by value.length often vary greatly, with the actual words. Usually the real user complains. Obviously, I did not write so many words, but the system prompted more than the word limit. Then, I learned the word rule, which is used to calculate the number of words. He wrote a number of such programs."Reference Code"Use Word to calculate body Word function fngetcpmiswords (str) {slen

Table of contestants in a Grand Prix In the "Final score" item, we use the internal average value function provided by ET--trimmean to compute the formula: =trimmean (B3:I3,2/8) Here's a look at the Trimmean function: The function of the Trimmean function is to return the internal average of the dataset. function Trimmean First removes a percentage of data points from the head and tail of the array, and then averages them. You can use this function

When using the STM32 ADC for the detection voltage must be back to the calculation of the voltage value, in order to obtain more efficient voltage, there are now the following three ways:You get the result that the voltage value on your current ad pin is converted to a number relative to 3.3V and 4096.If you get the ad result is ADC_DR this variable, they have the following relationship:adc_dr/Current Voltage value = 4096/3300 MV If you want the curre
