Removing reference to local installed package

Greetings everybody, I installed a local package using python -m pip install Now if you install the same package from pypi, it says requirements already satisfied pointing to the location of the local package folder instead of site -package pip uninstall does not work as the package is not in

Floating point overflow and underflow

In Python3 an operation as follows: >>> 10135.1941 * (10**8) gives the result: 101351941.0001 Similarly, using the pow function also gives the same overflow/underflow error. >>> 10135.1941 * pow(10,8) 101351941.0001 Like multiplication, division of large or very small floating point numbe

Thanks Rob. How would one initialize a Decimal with something like pow(2,256)? On Tue, Jan 7, 2020 at 5:25 PM Rob Gaddi wrote: > On 1/7/20 3:47 PM, Shashank Tiwari wrote: > > In Python3 an operation as follows: > 10135.1941 * (10**8) > > gives the result: 101351941.0001 > > > > Similar
