In NASM, it's possible to define integer constants (equ), however, doing the same with floating point values causes an error:

section .data
    c1 equ 3       ; ok
    v2 dq  3.14    ; ok
    c2 equ 3.14    ; not ok: `my.asm:7: error: expression syntax error`

is it possible to define a floating point constant?

I've check the manual, but there's very little information.
