Floating point in Assembly

[ombadboy]

Can someone suggest me a method to convert a floating point number into binary using assembly?

for example 5.5 would be 000..101.1

but how would you go on about this in assembly?

Enter 5.5, look at the bit pattern.

Look familiar?

ye ye.. but how would you go on about doing that in assembly?

i mean.. u can convert a floating point to a binary by continuously diving the remainder by 2, and 'saving' the quotient of the division whether its 1 or 0, and form the binary.

The problem that arises with this solution is that only 8 registers are provided, so that would lead to only allowing you to display a binary of 8 bits long (only).

It's already stored in binary, so you just take the mantissa and output a string of 0 and 1. Assuming you've done this exercise for int, then then this step at least is no different.

You then use the exponent to work out where the radix point . goes.
