NAME

       Tk::Font - a class for finding X Fonts

SYNOPSIS

	use Tk::X11Font;

	$font = $widget->X11Font(foundry => 'adobe',
			      family  => 'times',
			      point   => 120
			     );

	$font = $widget->X11Font('*-courier-medium-r-normal-*-*');

DESCRIPTION

	  This module can be use to interrogate the X server what fonts are
	  avaliable.

METHODS

   Foundry( [ $val ] )
   Family( [ $val ] )
   Weight( [ $val ] )
   Slant( [ $val ] )
   Swidth( [ $val ] )
   Adstyle( [ $val ] )
   Pixel( [ $val ] )
   Point( [ $val ] )
   Xres( [ $val ] )
   Yres( [ $val ] )
   Space( [ $val ] )
   Avgwidth( [ $val ] )
   Registry( [ $val ] )
   Encoding( [ $val ] )
       Set the given field in the font name to $val if given and return the current or previous value

   Name( [ $max ] )
       In a list context it returns a list of all font names that match the fields given. It will return a maximum of $max names, or 128 if $max
       is not given.

       In a scalar contex it returns the first matching name or undef

   Clone( [ key => value, [ ...]] )
       Create a duplicate of the curent font object and modify the given fields

NAME

       Complex - Complex numbers.

Module
       Module	Complex

Documentation
       Module Complex
	: sig end

       Complex numbers.

       This  module  provides arithmetic operations on complex numbers.  Complex numbers are represented by their real and imaginary parts (carte-
       sian representation).  Each part is represented by a double-precision floating-point number (type float ).

       type t = {
	re : float ;
	im : float ;
	}

       The type of complex numbers.  re is the real part and im the imaginary part.

       val zero : t

       The complex number 0 .

       val one : t

       The complex number 1 .

       val i : t

       The complex number i .

       val neg : t -> t

       Unary negation.

       val conj : t -> t

       Conjugate: given the complex x + i.y , returns x - i.y .

       val add : t -> t -> t

       Addition

       val sub : t -> t -> t

       Subtraction

       val mul : t -> t -> t

       Multiplication

       val inv : t -> t

       Multiplicative inverse ( 1/z ).

       val div : t -> t -> t

       Division

       val sqrt : t -> t

       Square root.  The result x + i.y is such that x > 0 or x = 0 and y >= 0 .  This function has a discontinuity along the negative real axis.

       val norm2 : t -> float

       Norm squared: given x + i.y , returns x^2 + y^2 .

       val norm : t -> float

       Norm: given x + i.y , returns sqrt(x^2 + y^2) .

       val arg : t -> float

       Argument.  The argument of a complex number is the angle in the complex plane between the positive real axis and  a  line  passing  through
       zero and the number.  This angle ranges from -pi to pi .  This function has a discontinuity along the negative real axis.

       val polar : float -> float -> t

       polar norm arg returns the complex having norm norm and argument arg .

       val exp : t -> t

       Exponentiation.	exp z returns e to the z power.

       val log : t -> t

       Natural logarithm (in base e ).

       val pow : t -> t -> t

       Power function.	pow z1 z2 returns z1 to the z2 power.
