realmax - Largest positive floating-point number
Syntax
n = realmax
Description
n = realmax returns the largest
floating-point number representable on your computer. Anything larger overflows.
realmax('double') is the same as realmax with
no arguments.
realmax('single') is the largest single precision
floating point number representable on your computer. Anything larger overflows
to single(Inf).
Examples
realmax is one bit less than 21024 or
about 1.7977e+308.
Algorithm
The realmax function is equivalent to pow2(2-eps,maxexp),
where maxexp is the largest possible floating-point exponent.
Execute type realmax to see maxexp for
various computers.
