Method Detail

getInstance

public static NumberUtils getInstance()

randomNonNegativeLong

public static long randomNonNegativeLong()

min

public static int min(int a,
                      int b)

max

public static int max(int a,
                      int b)

round

public static double round(double val,
                           int places)

round

public static float round(float val,
                          int places)

padWithZeroes

public static String padWithZeroes(Number value,
                                   int numberOfZeroes)

stringToDouble

@Deprecated
public static double stringToDouble(String s)

Deprecated.

since 4.2 consider using createDoubleQuietly(String)

Returns:

createDoubleQuietly

@Nullable
public static @Nullable Double createDoubleQuietly(@Nullable
                                                   @Nullable String s)

see NumberUtils.createDouble(String). Returns null instead of throwing an exception.

unlocalizedStringToDouble

public static double unlocalizedStringToDouble(@Nullable
                                               @Nullable String s)

Convert string to double value. Method expects non-localized input (as produced by Double.toString(double)). If the input cannot be parsed method would log this and return 0.

This method is intended to be used from FreeMarker code.

Parameters:

s - input string containing representation of a double value.

Returns:

parsed value or 0 if there was error during parsing

stringToLong

public static long stringToLong(String s)

stringToInt

public static int stringToInt(String s)

max

public static <T extends Comparable<? super T>> T max(@NotNull
                                                      @NotNull Collection<T> collection)

isPositiveInteger

public static boolean isPositiveInteger(@Nullable
                                        @Nullable String input)

arrayStore

public static void arrayStore(int number,
                              @NotNull
                              @org.jetbrains.annotations.NotNull byte[] array,
                              int startIndex)

arrayStore

public static void arrayStore(long number,
                              @NotNull
                              @org.jetbrains.annotations.NotNull byte[] array,
                              int startIndex)

valueOf

public static long valueOf(Long l,
                           long defaultValue)

Null-safe unboxing of Long

Parameters:

l - value to unbox

defaultValue - default value to return if l is null

toInteger

@Nullable
public static @Nullable Integer toInteger(@Nullable
                                          @Nullable Number number)
