decimal

I am trying to add two decimal values but the returned sum is pure integer. What is wrong? I can't find it. any help will be welcome. jQuery(".delivery-method #ship_select").change(function(){ var cost = jQuery(this).val(); jQuery("#delivery_cost").val(cost); //returns 20.00 var tot = parseInt(cost) + parseInt(total); //total returns 71.96 }); With the code i am getting only 91 and not 91.96 Use parseFloat() instead of parseInt() . jQuery(".delivery-method #ship_select").change(function(){ var cost = jQuery(this).val(); jQuery("#delivery_cost").val(cost); //returns 20.00 var tot = parseFloat

Direct conversion from float to Decimal was implemented in python-2.7, both in Decimal's constructor and with the Decimal.from_float() classmethod. Python-2.6 instead throws a TypeError suggesting to convert to string first: TypeError: Cannot convert float to Decimal. First convert the float to a string so my usual workaround is this: if sys.version_info < (2, 7): Decimal.from_float = classmethod(lambda cls, x: cls(str(x))) That's just a literary translation from the error message - and I just don't bother implementing it in the constructor too. If it's that simple, why didn't they implement

During a conversation on IRC, someone pointed out the following: decimal.Parse("1.0000").ToString() // 1.0000 decimal.Parse("1.00").ToString() // 1.00 How/why does the decimal type retain precision (or, rather, significant figures) like this? I was under the impression that the two values are equal, not distinct. This also raises further questions: How is the number of significant figures decided during mathematical operations? Does the number of significant figures get retained during serialization? Does the current culture affect the way this is handled? How is the number of significant

The Double data type cannot correctly represent some base 10 values. This is because of how floating point numbers represent real numbers. What this means is that when representing monetary values, one should use the decimal value type to prevent errors. (feel free to correct errors in this preamble) What I want to know is what are the values which present such a problem under the Double data-type under a 64 bit architecture in the standard .Net framework (C# if that makes a difference) ? I expect the answer the be a formula or rule to find such values but I would also like some example values

I need to work with decimals. In my program, the user need to put a number with decimals to convert that number. The problem is: If I try to convert the argument into a number I get a integer without decimals. # ARGV[0] is: 44.33 size = ARGV[0] puts size.to_i # size is: 44 # :( You call to_i , you get integer. Try calling to_f , you should get a float. For more string conversion methods, look here . If you want more accurate answer with the calculation to avoid bug like this https://www.codecademy.com/en/forum_questions/50fe886f68fc44056f00626c you can use conversion to decimal example :

I can't seem to find this question anywhere on Google (or StackOverflow), which really surprised me, so I'm putting it on here to help others in the same situation. I have a SQL query which runs fine on Oracle Sql Developer, but when I run it through C# using adapter.Fill(table) to get the results, I get Specified cast is not valid errors ( System.InvalidCastException ). Here is cut-down version of the C# code: var resultsTable = new DataTable(); using (var adapter = new OracleDataAdapter(cmd)) { var rows = adapter.Fill(resultsTable); // exception thrown here, but sql runs fine on Sql Dev
