Description
The ToDouble
function converts a value to a double-precision numeric
value, if possible.
Attempting to convert a value to a double-precision numeric value which has no numeric representation results in an "invalid argument" error.
Host languages have varying support for double-precision numeric
values. Within Fauna, double-precision numeric values are
stored and operated on as 64-bit, IEEE 754, double-precision float
values. The host language you use may affect how the result of
ToDouble can be interpreted.
