Determine if a real number is an integer type.

TF = isinteger(2)

TF =logical0

MATLAB® stores a real number as adoubletype by default.

Convert the number to a signed 8-bit integer type using theint8function. Check if it is an integer type.

TF = isinteger(int8(2))

TF =logical1

Determine if a complex number is an integer type.

A = 3.5 - 2.5i

A = 3.5000 - 2.5000i

TF = isinteger(A)

TF =logical0

MATLAB stores a complex number as adoubletype by default.

Convert the complex number into a signed 32-bit integer type using theint32function. Check if it is an integer type.

B =int32(A)

B =int324 - 3i

TF = isinteger(B)

TF =logical1

When a number with decimal digits is converted to an integer type, MATLAB rounds it to the nearest integer.

Determine if an array containing integer numbers is an integer type.

Create an array using theint8function. Check if it is an integer type.

A = [int8(1:5)]

A =1x5 int8 row vector1 2 3 4 5

TF = isinteger(A)

TF =logical1

现在，创建包含数组的单元数组Aand other integer numbers. Useclassto identify the type of the cell array. Check if it is an integer type.

b = {int8（-4）;INT8（2）INT8（1）}

B=2×2 cell array{1x5 int8} {[-4]} {[ 2]} {[ 1]}

type = class(B)

type = 'cell'

TF = isinteger(B)

TF =logical0

The cell array is not an integer type since it is a cell type.
