The third line uses throughout uint64 precision. Consider carefully if your problem really needs more precision.
Cordoza, 78, 84, Any of the MAT input and output statements may be used with a channel number to get input from a file or to print results to a printer or file. Arrays used with data files are very helpful in managing and manipulating large sets of related data.
If you print to a file and intend to input that data again later, you must print the data in an acceptable format. This process is known as redimensioning, although the word is somewhat misleading since the number of dimensions cannot be changed. The lower and upper bounds of each dimension, however, can be changed, and so the array may become larger or smaller.
Redimensioning has many uses. A typical use is to have the program ask the user for a list and its size, as in the example below.
This technique lets you use the same program for arrays with different number of elements, and it helps conserve memory by keeping arrays as small as possible.
Here is a similar example that reads an array from DATA statements: This example sets up the array, then reads the first two data items which are used to define the actual size of the table. With this trick, the program can work for tables of any size without your having to rewrite the program.
You need to change only the data lists in the DATA statements. The question mark in the statement instructs the program to accept a list of any length. True BASIC adjusts the upper bound of the subscript to make the size exactly right for the number of elements the user enters.
The user must separate items with commas and end a line with no comma to indicate the end of the input items. Note that you can use the question mark?
While this may be useful, you should be careful in using it, as shown below. Suppose that the 2-by-2 array sample contains the following values: But if you use the statement: Two precautions will prevent this problem.
A dimension of 0 effectively removes the array from memory, thus freeing the space it occupied. Therefore, when you need as much memory as you can muster, redimension any unnecessary arrays to zero ele- ments in each dimension.
Beware, however, that in doing so you will lose the contents of that array; use this tech- nique only when you no longer need the contents of an array.
Three functions may be used to discover the ranges of subscripts: If you omit the second argument d in the argument list of the SIZE function, the func- tion returns the total number of elements in the entire array.
For example, the following program inputs a list and prints it in reverse order: Not found Array Assignment As you have seen, loop structures provide a concise and convenient mechanism for processing the individual elements of an array in series.
The following program segment that copies the contents of one array into another: The following equivalent of the previous example shows how it simplifies array operations:Find helpful customer reviews and review ratings for Sharp EL-WB Scientific Calculator with WriteView (Black) at initiativeblog.com Read honest and unbiased product reviews from our users.

The following array formulas are used to calculate confidence intervals for Cohen’s effect size. Using R for psychological research A simple guide to an elegant language. This is one page of a series of tutorials for using R in psychological research.
This introduction to R is derived from an original set of notes describing the S and S-PLUS environments written in –2 by Bill Venables and David M.
Smith when at the University of Adelaide. We have made a number of small changes to reflect differences between the R and S programs, and expanded some of the material.

The CSS3 transform property can do some really cool things - with it, web designers can rotate, scale, skew and flip objects quite easily. However, in order for deisgners to have fine-grained, pixel level control over their transforms, it would be really helpful to understand how the matrix() function works.
With the matrix() function, designers can position and shape their transformations.
