# tosigned

Converts any kind of 8/16/32/64 integers to its corresponding signed integers. Available in version 5.2.0 and later.

## Prototype

```	function tosigned (
input_val  : any kind of 8/16/32/64 integers.
)

return_val [dimsizes(input_val)] :  signed 8/16/32/64 integers.
```

## Arguments

input_val

A variable of any kind of 8/16/32/64 integers.

## Return value

Returns corresponding 8/16/32/64 integers.

## Description

This function converts any kind of 8/16/32/64 integers to its corresponding signed integers. If there is any missing value, it will be converted as well.

## Examples

Example

```uv = new((/2/), ushort)
uv = 65535H
v = tosigned(uv)
print(uv)

;print-out:
;Variable: uv
;Type: ushort
;...
;(0)     65535
;(1)     65535

print(v)

;print-out:
;Variable: v
;Type: short
;...
;(0)     -1
;(1)     -1

nuv = tounsigned(v)
print(nuv)

;print-out:
;Variable: nuv
;Type: ushort
;...
;(0)     65535
;(1)     65535
```
Example

```ui = new((/2/), uint)
;ui = 2147483647I
ui = 4294967285I
i = tosigned(ui)
print(ui)
print(i)

nui = tounsigned(i)
print(nui)

ul = new((/2/), ulong)
;ul = 2147483647L
ul = 4294967285L
l = tosigned(ul)
print(ul)
print(l)

nul = tounsigned(l)
print(nul)

ull = new((/2/), uint64)
ull = 9223372036854775807Q
;ull = 18446744073709551615Q
ull = 2 * ull + 1;
ll = tosigned(ull)
print(ull)
print(ll)

mull = tounsigned(ll)
print(mull)
