float to string python
Some form of rounding is often unavoidable when dealing with floating point numbers. This is because numbers that you can express exactly in base 10 cannot always be expressed exactly in base 2 (which your computer uses). For example: >>> .1 0.10, With python < 3 (e.g. 2.6 [see comments] or 2.7), there are two ways to do so. # Option one older_method_string = "%.9f" % numvar # Option two newer_method_string = ":.9f}".format(numvar). But note that for python versions above 3 , You can use Series.astype method to convert float to int then to string, here I am using df to refer to the data frame you read in from csv and df.zip to refer to the zip column (adjust accordingly): df.zip.astype(int).astype(str).str.zfill(5) #0 00501 #, The format string :.2f} means "print a fixed-point number ( f ) with two places after the decimal point ( .2 )". str.format will automatically round the number correctly (assuming you entered the numbers with two decimal places in the first pla,Context() # 20 digits should be enough for everyone :D ctx.prec = 20 def float_to_str(f): """ Convert the given float to a string, without resorting to scientific notation """ d1 = ctx.create_decimal(repr(f)) return format(d1,for x in numbers: print ":10.4f}".format(x). prints 23.2300 0.1233 1.0000 4.2230 9887.2000. , You need to convert each entry of the list to a string, not the whole list at once: print " ".join(map(str, a)). If you want more control over the conversion to string (e.g. control how many digits to print), you can use print "".join,Formatting in Python is done via the string formatting ( % ) operator: "%02d:%02d:%02d" % (hours, ... Starting in Python 2.6, there is an alternative: the str.format() method. Here are some examples .... If you have a float that you want to igno, How can i convert a float value into a string value? Try: string_value1 = str(float_value) + ' abc' or: string_value1 = repr(float_value) + ' abc' Type in an interactive python session. help(str) or: help(repr) regards. Matt -- | Matt Ham, In Python, there are two number data types: integers and floating-point numbers or floats. Sometimes you are working on someone else's code and will need to convert an integer to a float or vice versa, or you may find that you have been using an inte
