iconvert
conversion to 1 to 8 byte integer representation
Syntax
y = iconvert(X, itype)
Arguments
- X
a matrix of decimal numbers, encoded integers, or booleans. Complex numbers are not supported.
- itype
an integer: conversion code
- y
matrix of integers encoded on 1, 2, 4 or 8 bytes, with the sizes of
X
:y(i)
isX(i)
converted into the chosen encoding.
Description
The iconvert
function converts and stores data to 1, 2, 4 or
8 bytes integers. Please refer to the int8() page for a
detailled description.
itype | y typeof | range |
---|---|---|
0 | (reals) | |
1 | int8 | [-128, 127] |
2 | int16 | [-32768, 32767] |
4 | int32 | [-2147483648, 2147483647] |
8 | int64 | [-9223372036854775808, 9223372036854775807] |
11 | uint8 | [0, 255] |
12 | uint16 | [0, 65535] |
14 | uint32 | [0, 4294967295] |
18 | uint64 | [0, 18446744073709551615] |
Converting [] always keeps it as is, of type 1 == inttype 0
(decimal type). |
Examples
iconvert([-3.6 -2.5 -1.2 1.2 2.5 3.6], 1) iconvert([-%inf %inf %nan], 1) iconvert([-%inf %inf %nan], 11) iconvert(-1, 11) iconvert(-1, 12) iconvert(-1, 14) iconvert(-1, 18)
--> iconvert([-3.6 -2.5 -1.2 1.2 2.5 3.6], 1) ans = -3 -2 -1 1 2 3 --> iconvert([-%inf %inf %nan], 1) ans = -128 127 0 --> iconvert([-%inf %inf %nan], 11) ans = 0 255 0 --> iconvert(-1, 11) ans = 255 --> iconvert(-1, 12) ans = 65535 --> iconvert(-1, 14) ans = 4294967295 --> iconvert(-1, 18) ans = 18446744073709551615
