n = realmax
realmax
is the largest floating-point number representable on a particular computer. Anything larger overflows.
realmax
is one bit less than 2^1024
or about 1.7977e+308.
realmax
is pow2(2-eps,maxexp)
where maxexp
is the largest possible floating-point exponent.
Execute type

to see maxexp
for various computers.
