Type conversions in simple variable types

Every simple variable type supports type conversion by invoking the constructor of the type.

int

Available for uint8, uint16, uint32/uint, uint64, int8, int16, int32/int and int64. When the conversion to an int fails, an exception is thrown.

Example

int("22") //is being converted to 22
int(1.5) //exception is thrown
int(true) //is being converted to 1

string

The string constructor accepts every type except for protos. Objects and structs are converted into JSON, other simple types are just being converted into strings (like with toString).

Example

string(21) //returns "21"
string(true) //returns "true"
string(22.3) //returns "true"

float

Available for float32/float as well as float64/double. When the conversion to a float fails, an exception is thrown.

Example

float("22") //returns 22.0
float("1.5") //returns 1.5
float(false) //returns 0.0
float(10) //returns 10.0

bool

When the conversion to a bool fails, an exception is thrown.

Example

bool(1) //returns true
bool("false") //returns false
bool(0.0) //returns false
bool("not a bool") //raises TypeConversionException

atom

Under the hood, the conversion to an atom will use toString. The conversion to an atom will only fail if one tries to convert a non-simple datatype.

Example

atom(1) //returns :1
atom(true) //returns :true
atom("ok") //returns :ok

pid

The only datatype that can be converted to a pid is an int. That is because the value of a pid is an int.
