Method Detail

isRepresentableAsInt

public static boolean isRepresentableAsInt(double number)

Returns true if double number can be represented as an int. Note that it returns true for negative zero. If you need to exclude negative zero, use JSType.isStrictlyRepresentableAsInt(double).

Parameters:

number - a double to inspect

Returns:

true for int representable doubles

isStrictlyRepresentableAsInt

public static boolean isStrictlyRepresentableAsInt(double number)

Returns true if double number can be represented as an int. Note that it returns false for negative zero. If you don't need to distinguish negative zero, use JSType.isRepresentableAsInt(double).

Parameters:

number - a double to inspect

Returns:

true for int representable doubles

isRepresentableAsLong

public static boolean isRepresentableAsLong(double number)

Returns true if double number can be represented as a long. Note that it returns true for negative zero. If you need to exclude negative zero, use JSType.isStrictlyRepresentableAsLong(double).

Parameters:

number - a double to inspect

Returns:

true for long representable doubles

isStrictlyRepresentableAsLong

public static boolean isStrictlyRepresentableAsLong(double number)

Returns true if double number can be represented as a long. Note that it returns false for negative zero. If you don't need to distinguish negative zero, use JSType.isRepresentableAsLong(double).

Parameters:

number - a double to inspect

Returns:

true for long representable doubles
