I am writing a class for handling decimal numbers, e.g. "123.456". I want one function for extracting the digits before the decimal point (123), and one function to extract the digits after the decimal point (0.456). My question is not how to do the programming, but how to name the functions? Do you have any better idea than digits_before_point() and digits_after_point()?
integralPart() and decimalPart() or integers() and decimals()
How about integral_part and decimal_part?
integer_part() and fraction_part()

I want to extract the decimal part of a number and use it as a column name. For example, extract “001“ from 0.001. Can I use decimalFormat for this?
Please refer to the script below using DolphinDB:
x=1.001
decimalFormat(x - floor(x), "0.000").substr(2)
The result is 001.
I am creating a program for a project that will help me learn visual basic. But when I work out how much a certain material is worth with dimensions. It come out with more than two decimal places. I know how to use math.floor function but it doesn't round to 2 decimal places.
Does anyone know what function I should use to round to two decimal places?
You can use;
Math.Round([DECIMAL], 2)
If you want to round up you can use;
MidpointRounding.AwayFromZero
As an additional parameter to make;
Math.Round([DECIMAL], 2, MidpointRounding.AwayFromZero)
Hope it helps!
The Decimal.Round method will do the trick for you.
You can specify the number of decimal places.
I'm trying to extract some numbers with decimals but need to remove the decimal part. There's no fixed length on any of both sides.
I have already tried:
INT()
INTR()
ROUND()
Usually INT() should solve this but sometimes it doesn't return the correct number (for example, INT(3) returns 2).
Did you try the function TRUNC(number, [, decimal_places]) ?
EDIT
For the round precision you can see this link
I ended up solving it on my own! ROUND didn't work and FLOOR was also undefined...
I ended up needing to use two INTs with a FORMAT in one of them.
Thank you anyway.
I've got a column called Amount, with a lot of numbers looking like this:
67000.00000000000000000000
Some of the columns have 2 numbers after the decimal that need to be retained.
Which should amount to $67,000.00
But my problem is, when I format it into currency or numbers, I get MUCH larger numbers than i would like, looking like this:
6.700.000.000.000.000.000.000.000,00
How can I get it into the right format?
Edit: For this scenario, the user was using ACC2013 and the Field Type was Short Text. The method of conversion that succeeded was : CCur(Val(FieldNameHere))
CCur(YourFieldName)
This will convert it to a currency format.
CLng(YourFieldName)
This will convert it to a long integer format. (It will cut off the decimals)
If you're looking for a reference, Microsoft has a few examples and goes into brief detail about some of these conversion functions.
CCur(Replace("67000.00000000000000000000", ".", Format(0, ".")))
You have to replace point symbol to actual decimal separator before conversion. Because you can't know actual seprator, choosen in regional settings, you have to find it out - and such Format() operation does dirty work.
The problem is that the SqlDecimal datatype packs more bits than the Decimal datatype which is native to the CLR. So how does one map between the two in the most practical way. This wohn't work that well:
SqlDecimal x = ...
decimal z = x.value; // can overflow
To have more numbers pass one can strip trailing zeros. But if you accept the loss of precision that the conversion gives you one would expect there'd be a function to do this lossy conversion.
Is there? Or what would be best practices here?
I've already made a function which both crops and removes trailing zeroes to do the conversion but I'd rather use a standard .NET BCL function if one such exists.
Use SqlDecimal.Round with a precision that matches the .NET decimal type.
