converting number to string in lisp

Question

I tried to find a lisp function to convert between numbers and strings and after a little googling I fond a function with the same name. when I entered `(itoa 1)` SLIME printed: ``` Undefined function ITOA called with arguments (1) . ``` How can I do the conversion?

Accepted Answer

From number to string:

```
(write-to-string 5)
"5"
```

you may transform a string to any numerical notation:

```
(write-to-string 341 :base 10)
"341"
```

From string to number:

```
(parse-integer "5")
5
```

with some trash

```
(parse-integer " 5 something not a number" :junk-allowed t)
5
```

Or use this:

```
(read-from-string "23 absd")
23
```
