intmax (MATLAB Functions)

Largest possible value of specified integer type

Syntax

```
v = intmax
v = intmax('classname')
```

Description

v = intmax is the largest positive value that can be represented in MATLAB 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'

`'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
```
