• Method Summary

  byte

  Returns the value of this Float as a byte after a narrowing primitive conversion.

  static int

  Compares the two specified float values.

  int

  Compares two Float objects numerically.

  Returns an

  Optional

  containing the nominal descriptor for this instance, which is the instance itself.

  double

  Returns the value of this Float as a double after a widening primitive conversion.

  boolean

  Compares this object against the specified object.

  static float

  Returns the float value closest to the numerical value of the argument, a floating-point binary16 value encoded in a short.

  static short

  Returns the floating-point binary16 value, encoded in a short, closest in value to the argument.

  static int

  Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.

  static int

  Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.

  float

  Returns the float value of this Float object.

  int

  Returns a hash code for this Float object.

  static int

  Returns a hash code for a float value; compatible with Float.hashCode().

  static float

  Returns the float value corresponding to a given bit representation.

  int

  Returns the value of this Float as an int after a narrowing primitive conversion.

  static boolean

  Returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).

  boolean

  Returns true if this Float value is infinitely large in magnitude, false otherwise.

  static boolean

  Returns true if the specified number is infinitely large in magnitude, false otherwise.

  boolean

  Returns true if this Float value is a Not-a-Number (NaN), false otherwise.

  static boolean

  Returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.

  long

  Returns value of this Float as a long after a narrowing primitive conversion.

  static float

  Returns the greater of two

  float

  values as if by calling

  Math.max

  .

  static float

  Returns the smaller of two

  float

  values as if by calling

  Math.min

  .

  static float

  Returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.

  Resolves this instance as a

  ConstantDesc

  , the result of which is the instance itself.

  short

  Returns the value of this Float as a short after a narrowing primitive conversion.

  static float

  Adds two float values together as per the + operator.

  Returns a hexadecimal string representation of the float argument.

  Returns a string representation of this Float object.

  Returns a string representation of the float argument.

  Returns a Float instance representing the specified float value.

  Returns a Float object holding the float value represented by the argument string s.
