The unit NUMIO contains a Delphi™ / C++ Builder visual component which supports the fail-safe input of numeric values. The user may select upon several numeric formats (binary, octal, three different decimal formats, and hexadecimal), and can optionally constrain the range of valid numbers. The component performs online type and range checking, so that the user is prevented from inputting any invalid numbers. At right you see a small application of a TNumIO control. The format of the yellow TNumIO control is switched to itHex, thus accepting hexadecimal numbers. The silver control below the TNumIO control displays the decimal representation of the entered hex value. More details can be found in the online help pages.

The unit NUMIO is part of the SDL Component Suite.
