I'm trying to collect some SMA data. Currently, the decimal place is auto limited to
0.000062
I need 2 more decimal places:
0.00006283
Here is my code:
symbol_df['5sma'] = symbol_df['close'].rolling(5).mean()
I've tried round, but no matter how high I set it, it's still limited to (6) decimal places.
This helped me out. I just placed it before the code and the correct decimal places were shown.
pd.set_option("display.precision", 8)

I made a blog that shows it current with and height in the displayed thext.
Now they have 4 decimal places (for example 5.600), see picture below.
I want them displayed with only 1 decimal place, how can i do this?
(example below would become 5.6x16.5 in stead of 5.6000x16.5000)
You can either modify the Precision property of the Field formatting so as to round the result to 1 decimal place:
Or, if you were looking to retain the precision, you could instead suppress trailing zeroes within the Additional Format options:
Alternatively, assuming that your formatting is set to Current units, you could change the value of your LUPREC system variable.
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 am looking for a way to create a masktextbox with a custom mask to allow only numbers and decimals. There can only be 2 decimal places & only one decimal point in place. Can this be done from a custom mask. I read the MSDN Doc related to mask but it doesn't seem to allow much flexibility or may be I am missing something, any details in this regard will be helpful.
Input for the mask textbox can be any number followed by 2 decimals (Optional).
Eg. 1200 or 1200.25 or 10
Based on Apple's documentation here: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/Strings/Articles/FormatStrings.html
It's pretty easy to understand the number to the right of the decimal point is the number of digis will be rounded up...
For example, %1.2f, 123456.123456 will turn out 123456.12 and %1.4f will turn out 123456.1234...
But it looks like the number to the left of decimal does nothing.
I tried changing the number to whatever I can think of, nothing happened.
What does it do?
The number before the decimal point in the format is called the format string's width. That is, if the resultant string would involves less characters than its width, it will be left-padded with blank spaces. You don't see any change because you either aren't using a high enough number (try something ridiculous like 100 or 200), or don't have a means of properly seeing your whitespace.
Can any one please help me how to get float value as it is from text box
for Ex: I have entered 40.7
rateField=[[rateField text] floatValue];
I am getting rateField value as 40.7000008 but I want 40.7 only.
please help me.
thanks in advance
Thanks Every body,
I tried all the possibilities but I am not able to get what I want. I am not looking to print the value to convert into string.I want to use that value for computation. If i use Number Formatter again when i am converting from number to float it is giving same problem.So i want float value only but it should be whatever i have given in the text box it should not be padded with any values.This is my requirement.Please help me.
thanks®ards Balu

This is ok. There is not guaranteed that you will get 40.7 if you will use even double.
If you want to output 40.7 you can use %.1f or NSNumberFormatter
Try using a double instead. Usually solves that issue. Has to do with the storage precision.
double dbl = [rateField.text doubleValue];
When using floating point numbers, these things can happen because of the way the numbers are stored in binary format in the computers memory.
It's similar to the way 1/3 = 0.33333333333333... in decimal numbers.
The best way to deal with this is to use number formatters in the textbox that displays the value.
You are already resolved float value.
Floating point numbers have limited precision. Although it depends on
the system, float relative error due to rounding will be around 1.1e-8
Non elementary arithmetic operations may give larger errors, and, of
course, error progragation must be considered when several operations
are compounded.
Additionally, rational numbers that are exactly representable as
floating point numbers in base 10, like 0.1 or 0.7, do not have an
exact representation as floating point numbers in base 2, which is
used internally, no matter the size of the mantissa. Hence, they
cannot be converted into their internal binary counterparts without a
small loss of precision. This can lead to confusing results: for
example, floor((0.1+0.7)*10) will usually return 7 instead of the
expected 8, since the internal representation will be something like
7.9999999999999991118....
So if you're using those numbers for output, you should use some rounding mechanism, even for double values.
