2int8, int16, int32, int64
Purpose Convert to signed integer
Syntax I = int8(X)
I = int16(X)
I = int32(X)
I = int64(X)
int8, int16, int32, int64
Description I = int*(X) converts the elements of array X into signed integers. X can be any
numeric object (such as a double). The results of an int* operation are shown
in the next table.
Operation Output Range Output Type Bytes per
Element
int8 -128 to 127 Signed 8-bit
integer
int16 -32,768 to 32,767 Signed 16-bit
integer
int32 -2,147,483,648 to 2,147,483,647 Signed 32-bit
integer
int64 -9,223,372,036,854,775,808 to
9,223,372,036,854,775,807
double and single values are rounded to the nearest int* value on conversion.
A value of X that is above or below the range for an integer class is mapped to
one of the endpoints of the range. For example,
int16(40000)
ans =
32767
Signed 64-bit
integer
1 int8
2 int16
4 int32
8 int64
Output Class
If X is already a signed integer of the same class, then int* has no effect.
You can define or overload your own methods for int* (as you can for any
object) by placing the appropriately named method in an @int* directory
within a directory on your path. Type help datatypes for the names of the
methods you can overload.
