I have done this before, but am now really confused. Created an array 'day' specifying the 'f' type In [29]: day Out[29]: array([ 5., 5.], dtype=float32) # Have a mask... In [30]: mask Out[30]: array([ True, False], dtype=bool) # So far, so good... In [31]: day[mask] Out[31]: array([ 5.], dtype=float32) In [32]: day[mask] = 10 # What? In [33]: day Out[33]: array([ 10., 10.], dtype=float32) So I created an integer array 'a' In [38]: a Out[38]: array([11, 1]) In [39]: a[mask] Out[39]: array([11]) In [40]: a[mask] = 12 # This is what I expect. In [41]: a Out[41]: array([12, 1]) Am I missing something? Is this supposed to happen? Version 1.7.1. Kindest regards, Tim
