The hash (#) only works inside macro blocks.

Code:

IntValz1 EQU 100
quat     dd 0,0

match v, IntValz1 {
  mov     [quat],v#.0
}

Some times this is not handfull and very easy forgot this.

Why not exist more simple mechanism ?
Like this for example:

Code:

IntValz1 EQU 100
mov     [vals],IntValz1(f)
mov     [vals],IntValz1(.0)
;or this
vals dd IntValz1,IntValz1(f)

The module that handles floats in fasm 1 is very limited and not easily extendable, while in fasmg the architecture was designed from ground up with such abilities in mind.

Very sad.
If create new method ?
Not EQU.
For example UVS

Undefined Value State.

Code:

data1 dd 0,0,0,0,0,0,0
MyVal UVS 100
mov [data1],MyVal#f
mov [data1],MyVal#.0

MyVal2 UVS 100,10,20,3
mov [data1],MyVal#f ;this unroll to four commands
