decimal

So here is what I am trying to accomplish. I have coordinate data in two tables, which I am trying to link together with an Association table. It is a one to one association, so if I have 40 records in table A, 40 records in table B, then I should have 40 records in the association table. Now the data in these two tables is approximately the same, but never idential, in fact they rarely even have the same precision. One table(we'll say A) always has 6 decimal places, whereas table B may have no decimal places or up to 6 decimal places. So let's say we're just matching up one pair of data, say,

The main question: How many digits? Let me explain. I have a number in binary system: 11000000 and in decimal is 192. After converting to decimal, how many digits it will have (in dicimal)? In my example, it's 3 digits. But, it isn't a problem. I've searched over internet and found one algorithm for integral part and one for fractional part. I'm not quite understand them, but (I think) they works. When converting from binary to octal, it's more easy: each 3 bits give you 1 digit in octal. Same for hex: each 4 bits = 1 hex digit. But, I'm very curious, what to do, if I have a number in P

I have value A of type DECIMAL(19,8) - the scale is 8 , so the number of decimal digits that will be stored to the right of the decimal point is 8 . Now, I am dividing A on B , where B is BIGINT . For, example: SELECT CAST(3 AS DECIMAL(19, 8)) / CAST(27 AS BIGINT) -- 0.111111111111111111111111111 ,CAST(300 AS DECIMAL(19, 8)) / CAST(27 AS BIGINT) -- 11.111111111111111111111111111 ,CAST(75003 AS DECIMAL(19, 8)) / CAST(13664400 AS BIGINT) -- 0.005488934750153684025643277 the output values are with length: 29 , 30 , 29 respectively. Could anyone tell why the length of the value for the three

I have some number of miles and a speed in MPH that I have converted into the number of hours it takes to travel that distance at that speed. Now I need to convert this decimal number into hours, minutes, and seconds. How do I do this? My best guess right now is: double time = distance / speed; int hours = time; // double to integer conversion chops off decimal int minutes = (time - hours) * 60; int seconds = (((time - hours) * 60) - minutes) * 60; Is this right? Is there a better way to do this? Thanks! I don't know c++ functions off the top of my head, however this "psuedocode" should work.

I have a text box of dollar amount ( html below ). I am trying to add some css or jquery to auto populate comma and decimal when user enters value in the text box. For eg , if the user enters 123456789 , it should automatically become 12,345,667.89 . <html:text styleId="incomePerPeriod" styleClass="textbox" property="employment.incomePerPeriod" maxlength="10" /> I added the below class to the html code above but it's not working. Can anyone please help me on how to achieve this ? class="form-control text-right number" It might be or might not be simpler by pure JS string functions but here is

What's the second minimum value that a decimal can represent? That is the value which is larger than Decimal.MinValue and smaller than any other values that a decimal can represent. How can I obtain this value in C#? Thanks! The second-minimum value is Decimal.MinValue + 1 . This can be inferred from the documentation for decimal : A decimal number is a floating-point value that consists of a sign, a numeric value where each digit in the value ranges from 0 to 9, and a scaling factor that indicates the position of a floating decimal point that separates the integral and fractional parts of the
