`intmin`

Smallest value of an integer class.

Category: Language Fundamentals > Data Types

Syntax

m = intmin

Returns the smallest int32.

m = intmin(classname)

Returns the smallest value of the named integer class.

Description

For signed types the smallest value is -2^(n-1), one unit further from zero than the largest is. For unsigned types it is 0. Subtracting past this value saturates instead of wrapping.

Input arguments

classname: An integer class name, default 'int32', or an integer array whose class is used.

Output arguments

m: Scalar of the requested class.

Example

Limits of integer classes

intmin
intmin('int8')
intmin('uint8')
intmin('int8') - 1

Output

ans = int32
   -2147483648
ans = int8
   -128
ans = uint8
   0
ans = int8
   -128
