问题 To begin with, allow me to confess that I'm an experienced programmer, who has over 10 years of programming experience. However, the question I'm asking here is the one, which has bugged me ever since, I first picked up a book on C about a decade back. Below is an excerpt from a book on Python, explaining about Python Floating type. Floating-point numbers are represented using the native double-precision (64-bit) representation of floating-point numbers on the machine. Normally this is IEEE

问题 I have a PDF template (designed using Adobe Livecycle designer), that has a subform and a textfield. The properties of those two objects is set to float . And the height of those objects is set to Autofit . All the enclosing parents heights of these objects were set to AutoFit .

问题 I'm programmatically putting various TextView s into a LinearLayout with a horizontal orientation. After 2h of research I couldn't find out how to tell Android not to squeeze all the TextViews in one line but instead to "float" non-fitting TextView s into the next line. I know there isn't something like actual "lines" in a LinearLayout , but how can I tell the TextView s to actually behave like floating DIVs from the HTML world? Thanks alot! 回答1: It sounds like you're looking for something

def function(): n=123.456 x=int(n) y=n-int(n) print(x,y) result: x= 123 y= 0.45600000000000307 how to get exactly .456 without using library function, n can be any floating number If you know from the outset that the number of decimal places is 3, then: y = round(n - int(n), 3) If you don't know the number of decimal places, then you can work it out, as so: y = round(n - int(n), str(n)[::-1].find('.')) As furas pointed out, you can also use the decimal package: from decimal import Decimal n = Decimal('123.456') y = n - int(n) You can also use the re module: import re def get_decimcal(n: float)

Calculate which numbers cause problems when converting decimal to floating point?

由 戏子无情 提交于 2019-12-08 12:32:41
问题 I know when converting some numbers from binary to floating point there can be problems. For example: 1.4 results in 1.39999. 6.2 is 6.1999999, 6.6 is 6.599999, etc. Is there a way to calculate which numbers will cause these problems? Like create some sort of spreadsheet or database with numbers from 1-50,000 which don't convert exactly? 回答1: The errors in floating point calculations are rooted in the way that floating point numbers are stored. Depending on which precision you are using

split float numbers in half with python

问题 I'm dealing with a csv table converted from a pdf with Adobe acrobat pro. For some reason the software creates recurrent error each 117 rows. It "duplicates & concatenates the numbers" e.g. a row 7307 1 87.1 is transformed into something of this sort: 73077307 11 87187.1 how I can "correct" these rows with python? I would need to split the float in the middle and erase the first half. I have read several threads about truncation but most of them need to split floats by the decimal point or
