How could you print decimal number to bynary nomber in foxpro?

I don't know of any specific function for that; you could write a user-defined function, that converts decimal to binary. In Visual FoxPro 9, transform() with a format code of "@0" will convert to hexadecimal; once you have that, it may be easier to convert each hexadecimal digit into 4 binary digits. I am not sure in what version of Visual FoxPro this option was introduced.A good forum for FoxPro and Visual FoxPro is www.universalthread.com; perhaps you can get additional information there.I don't know of any specific function for that; you could write a user-defined function, that converts decimal to binary.

What is a fast Fourier transform?

A fast Fourier transform is an efficient algorithm for working out the discrete Fourier transform - which itself is a Fourier transform on 'discrete' data, such as might be held on a computer. Contrast this to a 'continuous Fourier transform' on, say, a curve. One would need an infinite amount of data points to truly represent a curve, something that cannot be done with a computer.Check out: The Scientist And Engineer's Guide To Digital Signal Processing. It is a free, downloadable book that deals, inter alia, with Fourier transforms; chapters 8-12are germane to your question. This is a highly practical, roll-yer-sleeves-up book for, as the title says, scientists and engineers, but Smith describes the underlying theory well. The sample code supplied with the book is in BASIC and FORTRAN, of all things; the author does this for didactic purposes to make the examples easy to understand rather than efficient.
