* == What's Here
*
* First, what's elsewhere. \Class \Float:
*
* - Inherits from {class Numeric}[Numeric.html#class-Numeric-label-What-27s+Here].
*
* Here, class \Float provides methods for:
*
* - {Querying}[#class-Float-label-Querying]
* - {Comparing}[#class-Float-label-Comparing]
* - {Converting}[#class-Float-label-Converting]
*
* === Querying
*
* - #finite?:: Returns whether +self+ is finite.
* - #hash:: Returns the integer hash code for +self+.
* - #infinite?:: Returns whether +self+ is infinite.
* - #nan?:: Returns whether +self+ is a NaN (not-a-number).
*
* === Comparing
*
* - {<}[#method-i-3C]:: Returns whether +self+ is less than the given value.
* - {<=}[#method-i-3C-3D]:: Returns whether +self+ is less than
* or equal to the given value.
* - {<=>}[#method-i-3C-3D-3E]:: Returns a number indicating whether +self+ is less than,
* equal to, or greater than the given value.
* - {==}[#method-i-3D-3D] (aliased as #=== and #eql>):: Returns whether +self+ is
* equal to the given value.
* - {>}[#method-i-3E]:: Returns whether +self+ is greater than the given value.
* - {>=}[#method-i-3E-3D]:: Returns whether +self+ is greater than
* or equal to the given value.
*
* === Converting
*
* - #% (aliased as #modulo):: Returns +self+ modulo the given value.
* - #*:: Returns the product of +self+ and the given value.
* - {**}[#method-i-2A-2A]:: Returns the value of +self+ raised to the power of the given value.
* - #+:: Returns the sum of +self+ and the given value.
* - #-:: Returns the difference of +self+ and the given value.
* - {/}[#method-i-2F]:: Returns the quotient of +self+ and the given value.
* - #ceil:: Returns the smallest number greater than or equal to +self+.
* - #coerce:: Returns a 2-element array containing the given value converted to a \Float
and +self+
* - #divmod:: Returns a 2-element array containing the quotient and remainder
* results of dividing +self+ by the given value.
* - #fdiv:: Returns the Float result of dividing +self+ by the given value.
* - #floor:: Returns the greatest number smaller than or equal to +self+.
* - #next_float:: Returns the next-larger representable \Float.
* - #prev_float:: Returns the next-smaller representable \Float.
* - #quo:: Returns the quotient from dividing +self+ by the given value.
* - #round:: Returns +self+ rounded to the nearest value, to a given precision.
* - #to_i (aliased as #to_int):: Returns +self+ truncated to an Integer.
* - #to_s (aliased as #inspect):: Returns a string containing the place-value
* representation of +self+ in the given radix.
* - #truncate:: Returns +self+ truncated to a given precision.
