-.SH DESCRIPTION
-.PP
-Tcl allows a number of mathematical functions to be used in
-expressions, such as \fBsin\fR, \fBcos\fR, and \fBhypot\fR.
-These functions are represented by commands in the namespace,
-\fBtcl::mathfunc\fR.  The \fBTcl_CreateMathFunc\fR function is
-an obsolete way for applications to add additional functions
-to those already provided by Tcl or to replace existing functions.
-It should not be used by new applications, which should create
-math functions using \fBTcl_CreateObjCommand\fR to create a command
-in the \fBtcl::mathfunc\fR namespace.
-.PP
-In the \fBTcl_CreateMathFunc\fR interface,
-\fIName\fR is the name of the function as it will appear in expressions.
-If \fIname\fR does not already exist in the \fB::tcl::mathfunc\fR
-namespace, then a new command is created in that namespace.
-If \fIname\fR does exist, then the existing function is replaced.
-\fINumArgs\fR and \fIargTypes\fR describe the arguments to the function.
-Each entry in the \fIargTypes\fR array must be
-one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR, \fBTCL_WIDE_INT\fR,
-or \fBTCL_EITHER\fR to indicate whether the corresponding argument must be an
-integer, a double-precision floating value, a wide (64-bit) integer,
-or any, respectively.
-.PP
-Whenever the function is invoked in an expression Tcl will invoke
-\fIproc\fR.  \fIProc\fR should have arguments and result that match
-the type \fBTcl_MathProc\fR:
-.PP
-.CS
-typedef int \fBTcl_MathProc\fR(
-        ClientData \fIclientData\fR,
-        Tcl_Interp *\fIinterp\fR,
-        Tcl_Value *\fIargs\fR,
-        Tcl_Value *\fIresultPtr\fR);
-.CE
-.PP
-When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
-arguments will be the same as those passed to \fBTcl_CreateMathFunc\fR.
-\fIArgs\fR will point to an array of \fInumArgs\fR Tcl_Value structures,
-which describe the actual arguments to the function:
-.PP
-.CS
-typedef struct Tcl_Value {
-    Tcl_ValueType \fItype\fR;
-    long \fIintValue\fR;
-    double \fIdoubleValue\fR;
-    Tcl_WideInt \fIwideValue\fR;
-} \fBTcl_Value\fR;
-.CE
-.PP
-The \fItype\fR field indicates the type of the argument and is
-one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR.
-It will match the \fIargTypes\fR value specified for the function unless
-the \fIargTypes\fR value was \fBTCL_EITHER\fR. Tcl converts
-the argument supplied in the expression to the type requested in
-\fIargTypes\fR, if that is necessary.
-Depending on the value of the \fItype\fR field, the \fIintValue\fR,
-\fIdoubleValue\fR or \fIwideValue\fR
-field will contain the actual value of the argument.
-.PP
-\fIProc\fR should compute its result and store it either as an integer
-in \fIresultPtr->intValue\fR or as a floating value in
-\fIresultPtr->doubleValue\fR.
-It should set also \fIresultPtr->type\fR to one of
-\fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR
-to indicate which value was set.
-Under normal circumstances \fIproc\fR should return \fBTCL_OK\fR.
-If an error occurs while executing the function, \fIproc\fR should
-return \fBTCL_ERROR\fR and leave an error message in the interpreter's result.
-.PP
-\fBTcl_GetMathFuncInfo\fR retrieves the values associated with
-function \fIname\fR that were passed to a preceding
-\fBTcl_CreateMathFunc\fR call.  Normally, the return code is
-\fBTCL_OK\fR but if the named function does not exist, \fBTCL_ERROR\fR
-is returned and an error message is placed in the interpreter's
-result.
-.PP
-If an error did not occur, the array reference placed in the variable
-pointed to by \fIargTypesPtr\fR is newly allocated, and should be
-released by passing it to \fBTcl_Free\fR.  Some functions (the
-standard set implemented in the core, and those defined by placing
-commands in the \fBtcl::mathfunc\fR namespace) do not have
-argument type information; attempting to retrieve values for
-them causes a NULL to be stored in the variable pointed to by
-\fIprocPtr\fR and the variable pointed to by \fIclientDataPtr\fR
-will not be modified.  The variable pointed to by \fInumArgsPointer\fR
-will contain -1, and no argument types will be stored in the variable
-pointed to by \fIargTypesPointer\fR.
-.PP
-\fBTcl_ListMathFuncs\fR returns a Tcl value containing a list of all
-the math functions defined in the interpreter whose name matches
-\fIpattern\fR.  The returned value has a reference count of zero.

-.PP
-\fINote: the \fBcase\fI command is obsolete and is supported only
-for backward compatibility.  At some point in the future it may be
-removed entirely.  You should use the \fBswitch\fI command instead.\fR
-.PP
-The \fBcase\fR command matches \fIstring\fR against each of
-the \fIpatList\fR arguments in order.
-Each \fIpatList\fR argument is a list of one or
-more patterns.  If any of these patterns matches \fIstring\fR then
-\fBcase\fR evaluates the following \fIbody\fR argument
-by passing it recursively to the Tcl interpreter and returns the result
-of that evaluation.
-Each \fIpatList\fR argument consists of a single
-pattern or list of patterns.  Each pattern may contain any of the wild-cards
-described under \fBstring match\fR.  If a \fIpatList\fR
-argument is \fBdefault\fR, the corresponding body will be evaluated
-if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
-matches \fIstring\fR and no default is given, then the \fBcase\fR
-command returns an empty string.
-.PP
-Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
-The first uses a separate argument for each of the patterns and commands;
-this form is convenient if substitutions are desired on some of the
-patterns or commands.
-The second form places all of the patterns and commands together into
-a single argument; the argument must have proper list structure, with
-the elements of the list being the patterns and commands.
-The second form makes it easy to construct multi-line case commands,
-since the braces around the whole list make it unnecessary to include a
-backslash at the end of each line.
-Since the \fIpatList\fR arguments are in braces in the second form,
-no command or variable substitutions are performed on them;  this makes
-the behavior of the second form different than the first form in some
-cases.

-The default value of 0 is special, meaning that Tcl should

-result of at most \fBtcl_precision\fR digits is an exact representation
-of the original number, the one that is closest to the original

-If the original number lies precisely between two equally accurate
-decimal representations, then the one with an even value for the least

-0.3125 will convert to 0.312, not 0.313, while 0.6875 will convert to
