IntegerConverter class

Converts arbitrary values into integers using extended conversion rules:

  • Strings are converted to floats, then to integers
  • DateTime: total number of milliseconds since unix epoсh
  • Boolean: 1 for true and 0 for false

Example

var value1 = IntegerConverter.toNullableInteger('ABC'); // Result: null
var value2 = IntegerConverter.toNullableInteger('123.456'); // Result: 123
var value3 = IntegerConverter.toNullableInteger(true); // Result: 1
var value4 = IntegerConverter.toNullableInteger( Date()); // Result: current milliseconds
