Assembler has floating point numbers,	by mwq	2003-12-19 05:27:29
On some machines Assembler has floating point	by JohnClarke	2003-12-19 05:54:11
but not on all. Admittedly it's not a problem with the current generation x86 and PowerPC machines, but the hardware wasn't always there to support it, and assembler doesn't provide instructions that aren't supported by the hardware. It's possible to do floating point arithmetic on an integer machine, but it's slow--you have to do a bunch of integer operations for each floating point operation. The best thing about the '486 was that it had a blazingly fast floating point processor compared to other microprocessors of the day--the first production micro with a full floating point processor on-chip IIRC. Symbolic math is fine for a lot of things, but it's not helpful for solving differential equations in realtime, which is what an antiaircraft battery has to do. And if the equation doesn't have a closed form solution then you end up making an approximation anyway.
