MIPS (or SPIM): Loading floating point numbers

Question

I am working on a little mini compiler while trying to learn some MIPS here. Here\'s my issue:

MIPS has an instruction li (load immediate) which would work like thi

Answer 1

You will need to use the floating point registers to load your floats.

Instead of:

li $5,2.5

Try:

li.s $f5,2.5

Take a look at mfc1 and mtc1 instructions to move between integer and floating point registers.
