c - Pow precision with unsigned longs -

-
so trying pow (x, y). x , y unsigned longs , result stored in unsigned long. result smaller 2^63 should able it. since returns floating point number inaccurate results big numbers. there anyway exact result without using external libraries bignum? know x*x y times, trying avoid because trying make program faster. pow function returns double has precision issues , when cast long precision issue. far know if dont use library not possible accurate result using pow function alone. you can @ exponentiation squaring , @ barak manos answer can try implement own pow function as unsigned long long pow(unsigned long long x,unsigned int y) { unsigned long long res = 1; while (y > 0) { if (y & 1) res *= x; y >>= 1; x *= x; } return res; }

Elixir macros: how to define function with dynamic arity -

refer post: how create dynamic function name using elixir macro? . the post above asked how use macro generate function without arguments, wonder how generate functions arguments ? assume there macro warp , write code like: warp fun, [args], :ok and generate code like: fun(args), do: :ok if want generate dynamic list of arguments, need use unquote_splicing this: defmacro warp(name, argument_names, code) quote def unquote(name)(unquote_splicing(argument_names)) unquote(code) end end end then later warp :foo, [a, b], {:ok, a, b} which generates def foo(a, b), do: {:ok, a, b} if call produce foo(1, 2) # {:ok, 1, 2} you can define macro without unquote_splicing , pass down combined name , arguments def : defmacro warp(name_and_args, do: code) quote def unquote(name_and_args) unquote(code) end end end this means need invoke warp invoke def , example: warp foo(a, b), do: {:ok, a, b}

java - How to index a super class property in Objectify when super class is not an @Entity -

arrays - A strange dot product in Python -

-
so have 2 matrices, 1 i×h , other i×i, h = m*i. take dot product of first m rows of first matrix first row of second, next m rows next row of second, etc. does know easy way in numpy? i'm trying avoid loop. import numpy np # examples = 5 m = 3 h = m * first = np.arange(h * i).reshape(h, i) # note dimension h×i, not i×h second = np.arange(i * i).reshape(i, i) # let's compute dot product of # every column of `first` # every column of `second` (i.e. every row of `second` transposed): # full_matrix_product = np.dot(first, second.transpose()) # no (explicit) loops, # more # multiplications # need in end. # extract specific dot products want: wanted_rows = np.arange(h) wanted_columns = np.arange(m).repeat(i) result = full_matrix_product[wanted_rows, wanted_columns].reshape(m, i)

list - Python - Repeated (second)) value in tuple -

-
assuming list follows: list1 = [('do not care1', 'some string'), ('do not care1', 'some new string'), ('do not care2', 'some string'), ('do not care3', 'some other stringa') ('do not care4', 'some other stringa') ('do not care10', 'some other stringb') ('do not care54', 'some string') i need entire entry if second value repeated more 2 times. in above example, want see output this 'do not care1', 'some string' 'do not care2', 'some string' 'do not care54', 'some string' how go doing this? you can use collections.counter , list comprehension : >>> form collections import counter >>> [i in list1 if i[1] in [item item,val in counter(zip(*list1)[1]).items() if val>2]] [('do not care1', 'some string'), ('do not care2', 'some string'
