>>15407635depends on what you're doing, if you want a good calc who doesn't fuck up and round all kinds of shit under your unwatchful eye you should strive for an rpn calc from Hewlett Packard
feel the nazi tech in your hands!
if you don't really give a fuck it's dropping terms and rounding errors buy a TI
if you like the numbers but you don't need serious math buy a Sharp
nothing else exists
