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:

BigDecimal extends the native Float class to provide the #to_d method.

When you require BigDecimal in your application, this method will be available on Float objects.

Constants

NAN = DBL2NUM(NAN)

INFINITY = DBL2NUM(INFINITY)

EPSILON = DBL2NUM(DBL_EPSILON)

MAX = DBL2NUM(DBL_MAX)

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

MAX_10_EXP = INT2FIX(DBL_MAX_10_EXP)

MIN_10_EXP = INT2FIX(DBL_MIN_10_EXP)

MAX_EXP = INT2FIX(DBL_MAX_EXP)

MIN_EXP = INT2FIX(DBL_MIN_EXP)

DIG = INT2FIX(DBL_DIG)

MANT_DIG = INT2FIX(DBL_MANT_DIG)

RADIX = INT2FIX(FLT_RADIX)

ROUNDS = Represents the rounding mode for floating point addition. Usually defaults to 1, rounding to the nearest number. Other modes include: -1:: Indeterminable 0:: Rounding towards zero 1:: Rounding to the nearest number 2:: Rounding towards positive infinity 3:
