== Overview ==
This This article details how to convert from one data type to another in [[Spel Reference Guide|Spel code]]. This concept is regarded as ''casting''.

== Details ==
Primary data types used in USD spel.
* string
* int
* float
* date
* duration
* uuid ''(introduced in r11.x)''

Example:
<source lang="javascript">string MyString;
int MyInt;
float MyFloat;
date MyDate;
duration MyDuration;
uuid MyUUID;

MyString = "Hello world no: " +(string) 1; // result: "Hello world no: 1"
MyInt = (int) "2 times"); // result: 2
MyFloat = (float)MyInt; // result: 2.00000
MyDate = (date)( (string) now()); // result: the actual date depending of your system time configuration
MyDuration = (duration)((int) "2" + 3), // result: duration of 5 sec.
MyUUID = (uuid)expand( "&{'mylogin'=cnt.userid->id}"); // result: the id of contact having userid "mylogin"</source>

Overloaded method to return a string within a string

string substr(string str, int start, int length)

string substr(string str, int start) // reads to the end of the string for finish

Can be used in conjuction with sindex to retrieve start index.

eg.

string myString;

string otherString;

otherString = "this is a string";

myString = substr(otherString,sindex(otherString,"a"));

// myString == "a string"

myString = substr(otherString,sindex(otherString,"is",4));

// myString == "is a"
