The floating point value class. The implementation of Float is the same as in C.
Arithmetic operator. Computes the sum, difference, product, quotient, remainder, and exponent.
Compares other with self; returns a positive integer if self is larger, 0 if the two are equal, and a negative integer if self is smaller.
Relational operator.
Returns TRUE even if the value is infinite, unless it is also NaN.
Returns 1 when a value is positive and infinite; returns -1 when a value is negative and infinite. Otherwise, returns nil. The floating point zero ensures infinite division.
inf = 1.0/0 p inf p inf.infinite? => Infinity 1 inf = -1.0/0 p inf p inf.infinite? => -Infinity -1
Returns TRUE when a value is NaN (not a number). The floating point zero ensures the result of division by 0 is NaN.
nan = 0.0/0.0 p nan p nan.nan? => NaN true
