I need to multiply an integer (two's compliment) by a floating point constant. Here is what I have:

.data
pi  dd 3.14
int dd 0ah


.code
fld pi

???

fmul ST(1), ST

How can I convert int to a floating point value for multiplying against pi?

So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster… >>> More
