Description:

public static int main (string[] args) {
	float f1 = 0.3f;
	float f2 = 3.4f;

	// Output: ``0.300000, 3.400000``
	print ("%f, %f\n", f1, f2);
	return 0;

Constants:

• public const int DIG
  Number of decimal digits that can be represented without losing precision
• public const float EPSILON
  Difference between 1.0 and the next representable value for float
• public const float 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 float MAX
  Maximum value of float
• public const int MAX_10_EXP
  Maximum positive integer such that 10 raised by power one more than that integer is a normalized float
• public const int MAX_EXP
  Maximum positive integer such that RADIX raised by power one more than that integer is a normalized float
• public const float MIN
  Minimum positive value of float, use - float.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 float
• public const int MIN_EXP
  Minimum negative integer such that RADIX raised by power one less than that integer is a normalized float
• public const float NAN
  Indicates that the value is not-a-number (NaN)
• public const int RADIX
  The radix (integer base) used by the representation of all three floating- point types
• public const int ROUNDS

Static methods:

• public static float max (float a, float b)
• public static float min (float a, float b)
• public static float parse (string str)
• public static bool try_parse (string str, out float result = null, out unowned string unparsed = null)

Methods:

• public float abs ()
• public float clamp (float low, float high)
• public bool is_finite ()
  Determines if the given floating point number has finite value i.e. it is normal, subnormal or zero, but not infinite or NAN.
• public int is_infinity ()
  Determines if the given floating point number is a negative or positive infinity
• public bool is_nan ()
  Determines if the given floating point number is not-a-number (NaN).
• public bool is_normal ()
  Determines if the given floating point number is normal, i.e. is neither zero, subnormal, infinite, nor NaN.
• public string to_string (string format = "%g")
  Similar to the standard C `sprintf()` function but safer, since it calculates the maximum space required and allocates memory to hold the result.
