Convert any real number from base 10 to base 2, i.e. (decimal with decimal point to its binary equivalent) for ex: 152.75------>10011000.11
API Declarations
' http://sherif1.netfirms.com/vbcode/binary.zip
' how to use:
' download the whole project from the link above or:
' use the functions in the code (dec , bin , u)
' **function "u" calculates the numbers of bits the binary # will be.
' **function "bin" converts the integer part of the # to its binary
' equivalent.
' **function "dec" converts the fraction part of the decimal #
' to its binary equivalent.
