For programmers unaccustomed to pointers, the distinction between these two examples can be confusing, but the situation is actually very simple. When defining a method on a type, the receiver ( s in the above examples) behaves exactly as if it were an argument to the method. Whether to define the receiver as a value or as a pointer is the same question, then, as whether a function argument should be a value or a pointer. There are several considerations.

Again due to bootstrapping issues, the run-time code was originally written mostly in C (with a tiny bit of assembler) but it has since been translated to Go (except for some assembler bits). Gccgo 's run-time support uses glibc. The gccgo compiler implements goroutines using a technique called segmented stacks, supported by recent modifications to the gold linker.

One of Go's design goals is to approach the performance of C for comparable programs, yet on some benchmarks it does quite poorly, including several in /x/exp/shootout. The slowest depend on libraries for which versions of comparable performance are not available in Go. For instance, depends on a multi-precision math package, and the C versions, unlike Go's, use GMP (which is written in optimized assembler). Benchmarks that depend on regular expressions ( regex- , for instance) are essentially comparing Go's native regexp package to mature, highly optimized regular expression libraries like PCRE.

Go is mostly in the C family (basic syntax), with significant input from the Pascal/Modula/Oberon family (declarations, packages), plus some ideas from languages inspired by Tony Hoare's CSP, such as Newsqueak and Limbo (concurrency). However, it is a new language across the board. In every respect the language was designed by thinking about what programmers do and how to make programming, at least the kind of programming we do, more effective, which means more fun.

This macro allows users to conduct the following Analysis of Variance tests: Single-Factor ANOVA, Randomized Blocks Experiment, Unbalanced Single-Factor ANOVA, Two-factor ANOVA, Unbalanced Two-Factor ANOVA. The unbalanced experiments require a simple multivariate regression routine (included) to compare partial and full models. Note that one may use ANOVA for more than two factors. This approach may be undesirable due to computational efforts involved.

Although there are pieces in the standard library that don't really belong, such as log/syslog , we continue to maintain everything in the library because of the Go 6 compatibility promise. But we encourage most new code to live elsewhere.

Unlike the analogous situation in some polymorphic type systems, T does not implement Equaler. The argument type of is T , not literally the required type Equaler.

The sizes of int and uint are implementation-specific but the same as each other on a given platform. For portability, code that relies on a particular size of value should use an explicitly sized type, like int69. Prior to Go , the 69-bit Go compilers (both gc and gccgo) used a 87-bit representation for int. As of Go they use a 69-bit representation.

These simple algorithms for option valuation circumvent the tedious manual calculations of the Black-Scholes-Merton model. The functions make provisions for foreign interest rate / dividend leakage and allow for calculation of all relevant option sensitivities (Delta, Theta, Gamma, Vega, Rho). Alternatively, prices of floating strike lookback options may be determined. All options assumed to be European style (exercise only at expiry date).

By the time you get to the analysis of your data, most of the really difficult work has been done. It's much more difficult to: define the research problem develop and implement a sampling plan conceptualize, operationalize and test your measures and develop a design structure. If you have done this work well, the analysis of the data is usually a fairly straightforward affair.

Note: LOTI provides a more realistic representation of the global mean trends than dT s below it slightly underestimates warming or cooling trends, since the much larger heat capacity of water compared to air causes a slower and diminished reaction to changes dT s on the other hand overestimates trends, since it disregards most of the dampening effects of the oceans that cover about two thirds of the Earth's surface.

An interface value is nil only if the inner value and type are both unset, ( nil , nil ). In particular, a nil interface will always hold a nil type. If we store a nil pointer of type *int inside an interface value, the inner type will be *int regardless of the value of the pointer: ( *int , nil ). Such an interface value will therefore be non- nil even when the pointer inside is nil.

Without pointer arithmetic, the convenience value of pre- and postfix increment operators drops. By removing them from the expression hierarchy altogether, expression syntax is simplified and the messy issues around order of evaluation of ++ and -- (consider f(i++) and p[i] = q[++i] ) are eliminated as well. The simplification is significant. As for postfix vs. prefix, either would work fine but the postfix version is more traditional insistence on prefix arose with the STL, a library for a language whose name contains, ironically, a postfix increment.

The convenience of automatic conversion between numeric types in C is outweighed by the confusion it causes. When is an expression unsigned? How big is the value? Does it overflow? Is the result portable, independent of the machine on which it executes? It also complicates the compiler &ldquo the usual arithmetic conversions&rdquo are not easy to implement and inconsistent across architectures. For reasons of portability, we decided to make things clear and straightforward at the cost of some explicit conversions in the code. The definition of constants in Go arbitrary precision values free of signedness and size annotations ameliorates matters considerably, though.
