I've been trying to read up on how to add to a float in assembly by using fadd, but cannot seem to grasp it.

The line of code that writes to the quickness address is:
Code:
movss [eax],xmm0


How would I add a small decimal increase to xmm0 so it is increased before it is stored into [eax]?

so how would you assign a small decimal value to, lets say, xmm4 to use addss

Code:

[somehow put a small decimal in xmm4]
addss xmm0,xmm4

To assign a value:
Code:
movss   xmm4, dword ptr ds:[nValue]

and
Code:
nValue  dd 0.5

or CE syntax
Code:
nValue:
dd 0.5
