// Declare an ee.Number. var number = ee . Number ( 100 ); print ( 'ee.Number:' , number ); // Cast a number to signed 64-bit integer. var longNumber = number . toLong (); print ( 'ee.Number cast to long:' , longNumber ); /** * Casting numbers to long that are outside of its range and precision can * modify the resulting value, note the behavior of the following scenarios. */ // A floating point number cast to long loses decimal precision. var float = ee . Number ( 1.7 ); print ( 'Floating point value:' , float ); var floatToLong = float . toLong (); print ( 'Floating point value cast to long:' , floatToLong );
