Enum DtoaMode

java.lang.Object

java.lang.Enum<DtoaMode>

com.oracle.truffle.js.runtime.doubleconv.DtoaMode

All Implemented Interfaces:

Serializable, Comparable<DtoaMode>, java.lang.constant.Constable

public enum DtoaMode
extends Enum<DtoaMode>

This defines the string conversion modes supported by this package. The original C++ library also supports SHORTEST-SINGLE for single precision floats but we don't since we always operate with doubles.

Enum Constant Detail

SHORTEST

public static final DtoaMode SHORTEST

Produce the shortest correct representation. For example the output of 0.299999999999999988897 is (the less accurate but correct) 0.3.

FIXED

public static final DtoaMode FIXED

Produce a fixed number of digits after the decimal point. For instance fixed(0.1, 4) becomes 0.1000 If the input number is big, the output will be big.

PRECISION

public static final DtoaMode PRECISION

Fixed number of digits (independent of the decimal point).

Method Detail

values

public static DtoaMode[] values()

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DtoaMode valueOf(String name)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
