intmax

Largest value of specified integer type

Syntax

v = intmax
v = intmax('classname')

Description

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

'int8'

'int16'

'int32'

'int64'

'uint8'

'uint16'

'uint32'

'uint64'

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

Examples

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

v = intmax('int64')
v =
  9223372036854775807

Convert this value to a 32-bit signed integer:

x = int32(v)
x =
  2147483647

Compare the result with the default value returned by intmax:

isequal(x, intmax)
ans =
     1
