Hello!
This is Basic FPU Float64 and Vector2D NASM MACROS!
Using NASM, GOLINK, GCC-MINGW64 (see below on "How to compile" section).
Entry:
Some time ago i created Float32 macros, but now, im on x64 machine, so, Float64 and Vector2D macros are needed.
If you know C \ C++, then:
- Float32 is 32 bit (or 4x byte) type named: float
- Float64 is 64 bit (or 8x byte) type named: double
These are previous x32 examples:
Float64 macros (fpu_float64_nasm_macros.asm):
- float64.push
- float64.pushv
- float64.set
- float64.pop
- float64.add
- float64.addv
- float64.sub
- float64.subv
- float64.mul
- float64.mulv
- float64.div
- float64.abs - absolute value
- float64.absv
- float64.sqrt - square root
- float64.sqrtv
- float64.chs - change sign
- float64.chsv
- float64.xch - swap
- float64.cmpv - experimental
- float64.cmp - experimental
Float64 comparison note (float64.cmpv, float64.cmp):
; Quote from book "The Art of Assembly Language"
; 14.4.7 Comparison Instructions:
; "..."
; "Since the sahf instruction does not copy"
; "any 80x87 processor status bits into the sign or"
; "overflow flags, you cannot use the jg , jl , jge , or jle instructions."
; "Instead, use the ja , jae , jb , jbe , je , and jz instructions"
; "when testing the results of a floating point comparison."
(fpu_float64_2d_vector_nasm_macros.asm):
; 2D VECTOR OFFSET STRUCTURE
VECTOR2D.X equ 8*0
VECTOR2D.Y equ 8*1
VECTOR2D_SIZE equ 8*2
Float64 Vector2D macros (fpu_float64_2d_vector_nasm_macros.asm):
- vector2d.push
- vector2d.pushv
- vector2d.set
- vector2d.pop
- vector2d.add
- vector2d.sub
- vector2d.mul
- vector2d.div
- vector2d.magnitude
- vector2d.normalize
- vector2d.normal
- vector2d.dot
