Float

v2_6_3 - Show latest stable - Superclass: Numeric

Float objects represent inexact real numbers using the native architecture’s double-precision floating point representation.

Floating point has a different arithmetic and is an inexact number. So you should know its esoteric system. See following:

Constants

DIG = INT2FIX(DBL_DIG)

EPSILON = DBL2NUM(DBL_EPSILON)

INFINITY = DBL2NUM(HUGE_VAL)

MANT_DIG = INT2FIX(DBL_MANT_DIG)

MAX = DBL2NUM(DBL_MAX)

MAX_10_EXP = INT2FIX(DBL_MAX_10_EXP)

MAX_EXP = INT2FIX(DBL_MAX_EXP)

MIN = The smallest positive normalized number in a double-precision floating point.\n\nUsually defaults to 2.2250738585072014e-308.\n\nIf the platform supports denormalized numbers,\nthere are numbers between zero and Float:

MIN_10_EXP = INT2FIX(DBL_MIN_10_EXP)

MIN_EXP = INT2FIX(DBL_MIN_EXP)

NAN = DBL2NUM(nan(""))

RADIX = INT2FIX(FLT_RADIX)

ROUNDS = Represents the rounding mode for floating point addition.\n\nUsually defaults to 1, rounding to the nearest number.\n\nOther modes include:\n\n-1:: Indeterminable\n0:: Rounding towards zero\n1:: Rounding to the nearest number\n2:: Rounding towards positive infinity\n3:
