BinDec converts binary to decimal, but what does Bin do? And do you convert Decimal to Binary?

It converts a binary string to a decimal
if
Bin%(101101) will come out to 45

It seems that BinDec converts binary to decimal, and Bin does too? Anyway I was looking through an ASM tutorial and it explained the conversions binry to decimal and decimal to binary so i wrote my own functions because i could only get your BinDec to work. Thanx for your help.
