Syntax

v = intmax

v = intmax(type)

Description

example

v = intmax returns the largest value of the 32-bit signed integer type.

example

v = intmax(type) returns the largest value of the specified integer type. When you convert a value that is larger than intmax(type) into the integer type type, the value becomes intmax(type).

Largest Value of 32-bit Signed Integer

Open Live Script

Return the largest value of the 32-bit signed integer type.

v = intmax

v = int32
    2147483647

Largest Value of 64-bit Unsigned Integer

Open Live Script

Return the largest value of the 64-bit unsigned integer type.

v = intmax('uint64')

v = uint64
    18446744073709551615

Check the class of v.

class(v)

ans = 
'uint64'

Convert Value Larger Than `intmax`

Open Live Script

Return the largest value of the 8-bit signed integer type, which is 127.

v = intmax('int8')

v = int8
    127

Convert a value larger than 127 to 8-bit signed integer.

v1 = int8(198)

v1 = int8
    127

The converted value becomes 127.

Check that v1 is the same as v.

isequal(v,v1)

ans = logical
