Description:
Converts from binary (base2) to decimal (base10). Provides a wrapper around the BIF InputBaseN. Converts both positive and negative numbers.

Return Values:
Returns a number.

Example:

<CFSET x='1111101000'>
<CFSET y='11111111111111111111110000011000'>
<CFOUTPUT>
#x# represented in decimal is: #BinToDec(x)#<BR>
#y# represented in decimal is: #BinToDec(y)#<BR>
</CFOUTPUT>

Parameters:
