Discover average value of numbers in iterable.

Parameters:iterable – iterable object
Returns:a number
>>> from blade.xmath import xaverage >>> xaverage([10, 40, 45]) 31.666666666666668

Discover how common each item in iterable is and the overall count of each item in iterable.

Parameters:iterable – iterable object
Returns:Collects namedtuple Count(least=int, most=int, overall=[(thing1, int), (thing2, int), ...])
>>> from blade.xmath import xcount >>> common = xcount([11, 3, 5, 11, 7, 3, 5, 11]) >>> # least common thing >>> common.least 7 >>> # most common thing >>> common.most 11 >>> # total count for every thing >>> common.overall [(11, 3), (3, 2), (5, 2), (7, 1)]

Discover the length of the smallest interval that can contain the value of every items in iterable.

Parameters:iterable – iterable object
Returns:a number
>>> from blade.xmath import xinterval >>> xinterval([3, 5, 7, 3, 11]) 8

Discover median value of numbers in iterable.

Parameters:iterable – iterable object
Returns:a number
>>> from blade.xmath import xmedian >>> xmedian([4, 5, 7, 2, 1]) 4 >>> xmedian([4, 5, 7, 2, 1, 8]) 4.5

Discover the minimum and maximum values among items in iterable.

Parameters:iterable – iterable object
Returns:namedtuple MinMAx(min=value, max=value).
>>> from blade.xmath import xminmax >>> minmax = xminmax([1, 2, 4]) >>> minmax.min 1 >>> minmax.max 4

Discover the total value of adding start and items in iterable together.

Parameters:
• iterable – iterable object
• start (int or float) – starting number
• precision (bool) – add floats with extended precision
>>> from blade.xmath import xsum >>> # default behavior >>> xsum([1, 2, 3]) 6 >>> # with a starting mumber >>> xsum([1, 2, 3], start=1) 7 >>> # add floating points with extended precision >>> xsum([.1, .1, .1, .1, .1, .1, .1, .1], precision=True) 0.8
