❮ Math Methods

System.out.println(Math.ulp(1.0));System.out.println(Math.ulp(1.0f));System.out.println(Math.ulp(5000000.0));System.out.println(Math.ulp(5000000.0f));System.out.println(Math.ulp(50000000.0));System.out.println(Math.ulp(50000000.0f));

Definition and Usage

Theulp() method returns the unit of least precision of a number.

The unit of least precision is the smallest step you can take up or down from a number. For example, the ulp for50000000.0f is 4.0, so the next number above it than can be represented with afloat data type is50000004.0f.

Note: Thedouble data type has a lot more precision than thefloat data type, so the ulp is smaller.

Note: Larger numbers have less precision than smaller numbers, that means the ulp is larger.

Note: The sign of a number does not affect the ulp.

Syntax

public static double ulp(doublenumber)

public static float ulp(floatnumber)
