Largest value of specific integer type

collapse all in page

Syntax

v = intmax
v = intmax(type)
v = intmax("like",p)

Description

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).

example

v = intmax("like",p) returns the largest value of the integer type with the same data type and complexity (real or complex) as the integer variable p.

Open Live Script

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

v = intmax
v = int32

2147483647
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'
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
   1
Open Live Script

Create a 2-by-3 complex array of 8-bit signed integers.

p = int8([-12 3+2i 2; 6 3 2-7i]);

Return the largest value of the integer type with the same data type and complexity as p.

v = intmax("like",p)
v = int8

127 +     0i

class(v)
ans = 
'int8'
