Constants:

  • public const int DIG
    Number of decimal digits that can be represented without losing precision
  • public const int DTOSTR_BUF_SIZE
    A good size for a buffer to be passed into [func@GLib.
  • public const double EPSILON
    Difference between 1.0 and the next representable value for double
  • public const double INFINITY
    Indicates that the value is not representable by the underlying type (positive or negative infinity)
  • public const int MANT_DIG
    Number of base RADIX digits that can be represented without losing precision
  • public const double MAX
    Maximum value of double
  • public const int MAX_10_EXP
    Maximum positive integer such that 10 raised by power one more than that integer is a normalized double
  • public const int MAX_EXP
    Maximum positive integer such that RADIX raised by power one more than that integer is a normalized double
  • public const double MIN
    Minimum positive value of double, use - double.MAX to get the minimum negative value
  • public const int MIN_10_EXP
    Minimum negative integer such that 10 raised by power one less than that integer is a normalized double
  • public const int MIN_EXP
    Minimum negative integer such that RADIX raised by power one less than that integer is a normalized double
  • public const double NAN
    Indicates that the value is not-a-number (NaN)

Static methods:

  • public static double max (double a, double b)
  • public static double min (double a, double b)
  • public static double parse (string str)
    Converts a string to a double value.
  • public static bool try_parse (string str, out double result = null, out unowned string unparsed = null)
    Converts a string to a double value.

Methods:

  • public double abs ()
  • public double clamp (double low, double high)
  • public unowned string format (char[] buffer, string format = "%g")
    Converts a `gdouble` to a string, using the '.
  • public bool is_finite ()
    Determines if the given double has finite value i.e. it is normal, subnormal or zero, but not infinite or NAN.
  • public int is_infinity ()
    Determines if the given double is a negative or positive infinity
  • public bool is_nan ()
    Determines if the double is not-a-number (NaN).
  • public bool is_normal ()
    Determines if the given double is normal, i.e. is neither zero, subnormal, infinite, nor NaN.
  • public unowned string to_str (char[] buffer)
    Converts a `gdouble` to a string, using the '.
  • public string to_string ()
    Converts the value to its equivalent string representation
