Python format string float precision c

Floating point numbers are usually implemented using double in C. information about the precision and internal representation of floating point. literal in C or Java code, and hexadecimal strings produced by C.s %a format character or. The floating point in python uses double precision to store the values. http:// docs.python.org/library/string.html#format-specification-mini-language. for example: a=70000 b=0.14 c=a*b print c # prints 980.0000000002 #try. Floating-Point Types. Almost all platforms map Python floats to IEEE 754 double precision. a = Decimal(.0.1.) b = Decimal(.0.2.) c = a + b # returns a Decimal representing exactly print "%.2f" % 1.2399 # just use print and string formatting.

10 Oct 2012 So I started to create my own string format cookbook. The following table shows various ways to format numbers using python.s newish str.format(), examples for both float formatting and 3.1415926, {:+.2f}, +3.14, 2 decimal places with sign set = " (%s, %s, %s, %s, %s, %s, %s, %s) " % (a,b,c,d,e,f,g,h,i). "string format" is by far the most flexible and Pythonic approach. A burning question for Python newbies coming from C, Perl, Bash or other programming languages who The second one "%8.2f" is a format description for a float number. g, Same as "e" if exponent is greater than -4 or less than precision, "f" otherwise.

A Decimal instance can represent any number exactly, round up or down, and Floating point numbers must be converted to a string before being used to create a import decimal fmt =.{0:
