DoubleConverter class

Converts arbitrary values into double using extended conversion rules:

• Strings are converted to double values
• DateTime: total number of milliseconds since unix epoсh
• Boolean: 1 for true and 0 for false

Example

var value1 = DoubleConverter.toNullableDouble('ABC'); // Result: null
var value2 = DoubleConverter.toNullableDouble('123.456'); // Result: 123.456
var value3 = DoubleConverter.toNullableDouble(true); // Result: 1
var value4 = DoubleConverter.toNullableDouble( Date()); // Result: current milliseconds
