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

Example

let value1 = LongConverter.toNullableLong("ABC"); // Result: null
let value2 = LongConverter.toNullableLong("123.456"); // Result: 123
let value3 = LongConverter.toNullableLong(true); // Result: 1
let value4 = LongConverter.toNullableLong(new Date()); // Result: current milliseconds
