BUG: Large distances between start and stop in np.linspace() result in non-finite values #21585
Closed as not planned
Description
Describe the issue:
I'm guessing some internal logic causes this issue, like in #20226. Given it's such an edge case this is probably not worth fixing, just thought I'd write an issue for prosperity's sake.
Reproduce the code example:
>>> np.linspace(-9.9792015476736e+291, 1.7976931348623157e+308, 1)
RuntimeWarning: overflow encountered in double_scalars
delta = stop - start
RuntimeWarning: invalid value encountered in multiply
y = y * delta
array([nan]) # expected -9.9792015476736e+291
>>> np.linspace(-9.9792015476736e+291, 1.7976931348623157e+308, 5)
... same warnings ...
array([ nan, inf, inf, inf, 1.79769313e+308] ) # expected finite values in-betweenNumPy/Python version information:
