[edit] Layout change proposal

How about we change the layout from tables to the list of members/constants, similar to most other pages? It gives us the ability to reference specific fnctions/constants individually from elsewhere, gives us a neat sidebar, and lets us expound on the details of any important member with examples and references within its own page, instead of being limited to a cell in a table. Who can tell from the table blurb what in the world does "tinyness_before" mean or how "digits10" is different from "max_digits10"?

Here's how it would look, right after the list of standard specializations,

[edit] Member constants

identifies types for which std::numeric_limits is specialized
(public static member constant)
[static]
identifies signed types
(public static member constant)
[static]
identifies integer types
(public static member constant)
[static]
identifies exact types
(public static member constant)
identifies floating-point types that can represent the special value "positive infinity"
(public static member constant)
identifies floating-point types that can represent the special value "quiet not-a-number" (NaN)
(public static member constant)
identifies floating-point types that can represent the special value "signaling not-a-number" (NaN)
(public static member constant)
[static]
identifies the denormalization style used by the floating-point type
(public static member constant)
identifies the floating-point types that detect loss of precision as denormalization loss rather than inexact result
(public static member constant)
[static]
identifies the rounding style used by the type
(public static member constant)
[static]
identifies the IEC 559/IEEE 754 floating-point types
(public static member constant)
[static]
identifies types that represent a finite set of values
(public static member constant)
[static]
identifies types that handle overflows with modulo arithmetic
(public static member constant)
[static]
number of radix digits that can be represented without change
(public static member constant)
[static]
number of decimal digits that can be represented without change
(public static member constant)
number of decimal digits necessary to differentiate all values of this type
(public static member constant)
[static]
the radix or integer base used by the representation of the given type
(public static member constant)
one more than the smallest negative power of the radix that is a valid normalized floating-point value
(public static member constant)
the smallest negative power of ten that is a valid normalized floating-point value
(public static member constant)
one more than the largest integer power of the radix that is a valid finite floating-point value
(public static member constant)
the largest integer power of 10 that is a valid finite floating-point value
(public static member constant)
[static]
identifies types which can cause arithmetic operations to trap
(public static member constant)
identifies floating-point types that detect tinyness before rounding
(public static member constant)

[edit] Member functions

[static]
returns the smallest finite value of the given type
(public static member function)
[static] (C++11)
returns the lowest finite value of the given type
(public static member function)
[static]
returns the largest finite value of the given type
(public static member function)
[static]
returns the difference between 1.0 and the next representable value of this type
(public static member function)
[static]
returns the maximum possible ISO 10967 rounding error for this type
(public static member function)
[static]
returns the positive infinity value of the given floating-point type
(public static member function)
[static]
returns the quiet NaN value of the given floating-point type
(public static member function)
returns the signaling NaN value of the given floating-point type
(public static member function)
[static]
returns the smallest positive denormalized value of the given floating-point type
(public static member function)

[edit] Helper classes

indicates floating-point rounding modes
(class)
indicates floating-point denormalization modes
(class)

And then within each page, we could list the default value for non-specialized numeric_limits, and the specified values for fundamental types (although the big at-a-glance table in the end of this page is useful too and should be kept, perhaps split between integer and floating-point though), give examples, etc.

Looks good to me. Something like this should've been implemented from the start.P12 11:05, 5 October 2011 (PDT)
Yup, much better. Nate 15:19, 7 October 2011 (PDT)
