... Only the lowest and highest bounds of the sequence of ranges are permitted to be of type UNDEFINED. For each range for which neither the lower or upper bound is of type UNDEFINED (ie, for each internal range in the sequence), the upper bound value must exceed the lower bound value unless both both bound types are INCLUSIVE, in which case the upper bound value may equal the lower bound value. In other words, each range must encompass some non-empty set of real numbers. ...

GIPSY applications programmers should be aware of the fact that the so called undefined value (or BLANK as it is called in FITS terminology) is a fixed value which can only be different across different computer operating systems. ... The subroutine SETFBLANK can be used to set one value to BLANK; subroutine SETFNBLANK sets a whole array to BLANK. For the sake of speed it is advisable to compare data values directly with the system defined BLANK instead of using the slower function FBLANK. ...

The following set of rules govern the evaluation of all shell variables. ... var signifies the value of var or nothing, if var is undefined. ${var} same as above except the braces enclose the name of the variable to be substituted. ${var-thing} value of var if var is defined; otherwise thing. $var is not set to thing. ${var=thing} value of var if var is defined; otherwise thing. If undefined $var is set to thing. ${var?message} If defined, $var; otherwise print message and exit the shell. ...

... The Boolean object is an object wrapper for a boolean value. ... JavaScript 1.3: added toSource method . ... If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false. All other values, including any object or the string "false" , create an object with an initial value of true. ... For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object. ...

A. Singh Institute of Mathematical Sciences, C.I.T. Chennai, India anupamk18@gmail.com Real elements in algebraic groups Let G be an algebraic group defined over a field k . ... Let G be a connected semisimple algebraic group of adjoint type defined over a perfect field k . ... It follows that if G is connected semisimple of adjoint type, with -1 in its Weyl group, then every semisimple element in G(k ) is strongly real in G(k ). This also shows that any regular element in such a group is real. ...

Deriving the sine or cosine of an arbitrary angle takes a bit more math than is covered here. ... Note first of all that a right-angled triangle contains two angles. ... Because the side opposite to A is the one adjacent to (90њ- A), it follows that the sine of one angle is the cosine of the other, and vice versa: . ... Consider the triangle PQR (drawing) with all three angles equal to 60њ. ... If we want the angle A to grow in equal steps of 15 o , we still need the sine and cosine of 15њ and 75њ. ...
