Matlab double function outputs infinity when taking a big number of type "sym" -


This literally I received the number (from the symsum function), which is of type sym:

= 328791078344903739363762093060350430076929707044786898291940722052812676355129485878814911641516759087483581972443760841410582114920781832660013389681326267351368505696628653562484228680842650173635989588528021721039959787053654401351638478786763875479187208098871238084448485336138651690856082810553570419028927840285091142054111375001

the I (in particular, to take the natural log) would like to change to make mathematical operations on numbers and therefore double, then double (a) simply " From inf Want Padn are ". How to go about this problem and change it from "Yoga" to a numerical type?

your number ~ 3.3x10 335 but the largest number of MATLAB Dual exact floating point can be displayed by numbers, ~ 1.8x10 308 (see the output of realmax ). Converting your number into double precision causes overflow because the number is larger, so can be represented so that MATLAB returns back to inf .

For a complete description of floating point representations and arithmetic, you see it

I use Django 1.6.5 with settings in my program txsite: DEBUG = true I set the lie to debug, but when I get the runner , I get the following error: CommandError: You have to set the settings. OLOWOWHESTS If DEBUG is False I ALLOWED_HOSTS = ['127.0.0.1', 'localhost'] but I get the same error. Does anyone know this address? Try ALLOWED_HOSTS = ['*'] Less secure If you are not on a firewall or public LAN, but what I use and it works.
