Type Casting / toDouble

toDouble(value, [failover])

Tries to coerce value into a double (64-bit floating point value). If value is a number, the conversion is direct. If value is a string, it is parsed to see if it represents a double. If not, type casting fails.

toDouble("38.772")

... returns 38.772

toDouble({Root Container.TextField.text}, 0.0)

... returns the value in the text box as a double, or 0.0 if the value doesn't represent an number.
