"""
If called without an argument, displays a floating point
number as 34.2 -- but only if there's a point to be displayed.
With a positive numeric argument, it displays that many decimal places
always.
With a negative numeric argument, it will display that many decimal
places -- but only if there's places to be displayed.
Examples:
Displays a float to a specified number of decimal places.
If called without an argument, it displays the floating point number with
one decimal place -- but only if there's a decimal place to be displayed:
* num1 = 34.23234
* num2 = 34.00000
* num1|floatformat results in 34.2
* num2|floatformat is 34
* num1|floatformat:3 is 34.232
* num2|floatformat:3 is 34.000
* num1|floatformat:-3 is 34.232
* num2|floatformat:-3 is 34
* num3 = 34.26000
* {{ num1|floatformat }} displays "34.2"
* {{ num2|floatformat }} displays "34"
* {{ num3|floatformat }} displays "34.3"
If arg is positive, it will always display exactly arg number of decimal
places:
* {{ num1|floatformat:3 }} displays "34.232"
* {{ num2|floatformat:3 }} displays "34.000"
* {{ num3|floatformat:3 }} displays "34.260"
If arg is negative, it will display arg number of decimal places -- but
only if there are places to be displayed:
* {{ num1|floatformat:"-3" }} displays "34.232"
* {{ num2|floatformat:"-3" }} displays "34"
* {{ num3|floatformat:"-3" }} displays "34.260"
