As defined in the Intel Software Manual page 830, FILD takes a memory operand, not an immediate:

DF /0 FILD m16int Valid Valid Push m16int onto the FPU register stack.
DB /0 FILD m32int Valid Valid Push m32int onto the FPU register stack.
DF /5 FILD m64int Valid Valid Push m64int onto the FPU register stack.

You want to define the constants in a data segment, and point to it. Something like:

.data 
hundred dd 100

; ....

.code
fild dword ptr [hundred]
