Largest value of specified integer type


v = intmax
v = intmax('classname')


v = intmax is the largest positive value that can be represented in the MATLAB® software with a 32-bit integer. Any value larger than the value returned by intmax saturates to the intmax value when cast to a 32-bit integer.

v = intmax('classname') is the largest positive value in the integer class classname. Valid values for the string classname are









intmax('int32') is the same as intmax with no arguments.


Find the maximum value for a 64-bit signed integer:

v = intmax('int64')
v =

Convert this value to a 32-bit signed integer:

x = int32(v)
x =

Compare the result with the default value returned by intmax:

isequal(x, intmax)
ans =
