102. The MATH Signature The signature math specifies basic mathematical constants, the square root function, and trigonometric, hyperbolic, exponential and logarithmic functions http://www.smlnj.org/doc/basis/pages/math.html

The Standard ML Basis Library The MATH signature The signature MATH specifies basic mathematical constants, the square root function, and trigonometric, hyperbolic, exponential and logarithmic functions based on a real type. The functions defined here have roughly the same semantics as their counterparts in ISO C's math.h The top-level structure Math provides these functions for the default real type Real.real In the functions below, unless specified otherwise, if any argument is a NaN, the return value is a NaN. In a list of rules specifying the behavior of a function in special cases, the first matching rule defines the semantics. Synopsis signature MATH structure Math MATH Interface type real val pi real val e real val sqrt val sin val cos val tan val asin val acos val atan val val exp val pow val ln val val sinh val cosh val tanh Description type real pi denotes the constant pi (3.141592653...). e denotes the base of the natural logarithm e sqrt x returns the square root of x sqrt . If x sin x cos x tan x return the sine, cosine and tangent, respectively, of x , measured in radians. If

104. Math::constants Here is the way you can do it with the mathconstants package package require mathconstants mathconstantsconstants radtodeg degtorad http://tcllib.sourceforge.net/doc/constants.html

NAME SYNOPSIS DESCRIPTION PROCEDURES ... KEYWORDS Package: tcllib, Version: CVS HEAD NAME math::constants - Mathematical and numerical constants SYNOPSIS package require Tcl ? 8.3 ? package require math::constants ::math::constants::constants args ::math::constants::print-constants args DESCRIPTION This package defines some common mathematical and numerical constants. By using the package you get consistent values for numbers like pi and ln(10). It defines two commands: One for importing the constants One for reporting which constants are defined and what values they actually have. The motivation for this package is that quite often, with (mathematical) computations, you need a good approximation to, say, the ratio of degrees to radians. You can, of course, define this like: and use the variable radtodeg whenever you need the conversion. This has two drawbacks: You need to remember the proper formula or value and that is error-prone. Especially with the use of mathematical functions like atan you assume that they have been accurately implemented. This is seldom or never the case and for each platform you can get subtle differences. Here is the way you can do it with the math::constants package: package require math::constants ::math::constants::constants radtodeg degtorad which creates two variables, radtodeg and (its reciprocal) degtorad in the calling namespace.

Published on XML.com http://www.xml.com/pub/a/2005/01/05/tr-xml.html See this if you're having trouble printing code examples Extending XSLT with EXSLT By Bob DuCharme In an earlier column titled XSLT Extensions , I described how the Extensions section of the XSLT 1.0 Recommendation provides a way to identify the use of extensions to the XSLT 1.0 language. If your XSLT processor implements specialized new elements and functions, this gives your stylesheet a standard way to declare them and to check whether the processor in use implements them. The good news is that, for example, a Java programmer using a Java-based XSLT implementation can add and use customized XPath functions in his or her stylesheets. The bad news is that this customization can kill the stylesheet's portability across XSLT processors. Unless... some hardworking XSLT devotees coordinate a collection of extensions to be implemented the same way by different XSLT processors. In early 2001, Leigh Dodds wrote in XML.com about how Jeni Tennison, Uche Ogbuji, David Carlisle, and others laid the ground work for EXSLT , a "a community initiative to provide extensions to XSLT." They've led this community effort to define a wide variety of extension elements and functions, and many useful functions are implemented identically in three of my four favorite XSLT processors:
