Simkin Built-in Functions

The following functions are available in all Simkin scripts.

There are comparatively few of these - applications embedding Simkin should provide a great deal more!

String handling

length(<value>)
this returns the length of the parameter (converted to a string)
For example:
```
a="1.0";
trace(length(a)); // will output "3" 
```
charAt(<value>,<pos>)
this returns the the character at position pos within the parameter value.
pos starts at 0 for the first character.
For example:
```
a="1.0";
trace(charAt(a,2)); // will output "0" 
```

Debugging Aids

trace(<value>)
this outputs a message to the tracer (as specified by the underlying application)
For example:
```
a="1.0";
trace(a); // will output "1.0" to the application tracer
```

Type Coercion Functions

toInt(<value>)
this returns a version of the parameter converted to an integer.
For example:
```
a="1.0";
trace(toInt(a)); // will output "1"
```
toFloat(<value>)
this returns a version of the parameter converted to a floating point value.
For example:
```
a="1";
trace(toFloat(a)); // will output "1.0000"
```
toString(<value>)
this returns a version of the parameter converted to a string.
For example:
```
a="1.0";
trace(toString(a)); // will output "1.0"
```
toChar(<value>)
this returns a version of the parameter converted to a character.
For example:
```
a="1.0";
trace(toChar(a)); // will output "1"
```
toBool(<value>)
this returns a version of the parameter converted to a boolean value.
For example:
```
a="1.0";
trace(toBool(a)); // will output "true"
```
isObject(<value>)
this returns true if the parameter is an object (as opposed to a number, string, character or boolean)
For example:
```
a="1.0";
trace(isObject(a)); // will output "false" 
trace(isObject(self)); // will output "true" 
```
