The format_spec field contains a specification of how the value should be presented, including such details as field width, alignment, padding, decimal precision and so on. You can use string formatting to format floating point numbers to a fixed width in Python. If not specified, then the field width will be determined by the content. '>' The field will be right-aligned within the available space. In this tutorial, you will learn how to convert a number into a floating-point number having a specific number of decimal points in Python programming language . The float() function allows the user to convert a given value into a floating-point number. The format field in the above SF_INFO structure is made up of the bit-wise OR of a major format type (values between 0x10000 and 0x08000000), a minor format type (with values less than 0x10000) and an optional endian-ness value. Preceding the width field by a zero (‘0’) character enables sign-aware zero-padding for numeric types. However, you can convert float to 3 decimal places also. This is the default for numbers. The empty string before the colon means “take the next provided argument to format()” – in this case the x as the only argument. The simplest case while calling the Python format function is to have a single formatter. '0' If the width field is preceded by a zero ('0') character, sign-aware zero-padding for numeric types will be enabled. The 10 is the total width of the field being printed, lefted-padded by spaces. You have to read further to convert the float to 2 decimal places in Python. If not specified, then the field width will be determined by the content. The 10.4f part after the colon is the format specification. ... '.format('Python Tutorial', 10) 'Python Tut' >>> Combining truncating and padding. Python format function. For example, if you want the decimal points to be aligned with width of 12 characters and 4 digits on the right of the decimal, you can use the following: >>> x = 12.35874 >>> print "{:12.4f}".format(x) 12.3587 Our float number 05.333 has to be formatted with 5 characters. The above example round the float to two decimal places. Formatting output using the format method : The format() method was added in Python(2.6). Width¶ width is a decimal integer defining the minimum field width. Round Float to Three Decimal Places Using format() of Python. The field will be left-aligned within the available space. Each replacement field contains either the numeric index of a positional argument or the name of a keyword argument. Below is the syntax to use it. 'width' is a decimal integer defining the minimum field width. This is usually the default for strings. the number following the “.” in our placeholder. You can invoke format function in one of the following ways: Single argument formatting. The f denotes fixed-point notation. If the width field is preceded by a zero ('0') character, this enables zero-padding. You can use string formatting to format floating point numbers to a fixed width in Python.For example, if you want the decimal points to be aligned with width of 12 characters and 2 digits on the right of the decimal, you can use the following: >>>x = 12.35874 >>>print "{:12.2f}".format(x) 12.36 The decimal part of the number or the precision is set to 2, i.e. Here are a few of the simple examples of the Python string formatting. Most built-in types support a common formatting mini-language, which is described in the next section. To convert float to two decimal places, you have to pass the third argument as ‘.3f‘. Finally, the last character “f” of our placeholder stands for “float”. This is equivalent to an alignment type of '=' and a fill character of '0'. This is equivalent to a fill character of ‘0’ with an alignment type of ‘=’. Each value type can define its own “formatting mini-language” or interpretation of the format_spec.. Python string format Width and Precision ... print '%10f' % 3.1415926 # Field width 10 print '%10.2f' % 3.1415926 # Field width 10, ... floatValue = 123456.789 print "Five digits after decimal in float %.5f" % floatValue The code above generates the following result.
