From fa9f9fd5639458b7865a48192c4dc18e7ef15d66 Mon Sep 17 00:00:00 2001 From: Anindya Srivastava Date: Fri, 1 Feb 2019 21:55:22 +0530 Subject: Type correction for the output of math.sqrt() Both in Python 2.7.10 and Python 3.6.5, math.sqrt() returns a float and not int. It seems like a tiny thing but sometimes may lead up to bigger confusions.
