intmin

Smallest value of specific integer type

collapse all in page

Syntax

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

Description

v = intmin returns the smallest value of the 32-bit signed integer type.

example

v = intmin(type) returns the smallest value of the specified integer type. When you convert a value that is smaller than intmin(type) into the integer type type, the value becomes intmin(type).

example

v = intmin("like",p) returns the smallest 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 smallest value of the 32-bit signed integer type.

v = intmin
v = int32

-2147483648
Open Live Script

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

v = intmin("uint64")
v = uint64

0

Check the class of v.

class(v)
ans = 
'uint64'
Open Live Script

Return the smallest value of the 8-bit signed integer type, which is –128.

v = intmin("int8")
v = int8

-128

Convert a value smaller than –128 to 8-bit signed integer.

v1 = int8(-135)
v1 = int8

-128

The converted value becomes –128.

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

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

-128 +      0i

class(v)
ans = 
'int8'
