WebApr 11, 2024 · Quantity promotes integer to floating types because it has a different default value for dtype than numpy – numpy.inexact versus None. For Quantity to use the same dtype inspection as numpy, use dtype=None. >>>. >>> q = u.Quantity(1, dtype=None) >>> np.issubdtype(q.dtype, np.integer) True. WebVector Subtraction Examples Example 1: Compute the vector subtraction a - b if a = <1, -2, 5> and b = <3, -1, 2>. Also, find its magnitude. Solution: Given that a = <1, -2, 5> and b = <3, -1, 2>. Now we will find their difference by subtracting the respective components. a - b = <1, -2, 5> - <3, -1, 2> = <1 - 3, -2 - (-1), 5 - 2> = <-2, -1, 3>
