isSafeInteger

• isSafeInteger(x: number): boolean

• Tests if a finite double-precision floating-point number is a safe integer.

  Notes

  • An integer valued number is "safe" when the number can be exactly represented as a double-precision floating-point number.

  Parameters

  • x: number

    value to test

  Returns boolean

  boolean indicating whether the value is a safe integer

  Example

  var bool = isSafeInteger( 1.0 );
  // returns true

  Example

  var bool = isSafeInteger( 2.0e200 );
  // returns false

  Example

  var bool = isSafeInteger( 3.14 );
  // returns false
