Hello I i want a byte worth from memory reading and this dan in a float worth umwandel and then on the FPU tab ST(0) with the Assembler commands fild send my trouble is that I not white How one with Assembler a byte worth in a Float worth umwandelt and my investigation Internet too without success was. would be me very forward and grateful his if me the someone demonstrating could How the goes.

byte in Long and Long in Float, byte in Long:
Compile Mark Separation

xor eax,eax
mov eax,byteWerte>

and Long To Float will need you hold a Mem for the Sourcelong and a Mem for Targetfloat:
Compile Mark Separation

local dwo:dword
local flo:qword
mov eax,longWert
mov dwo,eax
lea eax,dwo
lea ebx,flo
finit
fild dword ptr [eax]//load dword
fstp qword ptr [ebx]//store floa

where then in Float flo the Longwert from dwo lying, wg. st(0) look at fstp. with XPSE can simply float(bytewert) [...]

write, circa a Bytewert to Float To konvertieren.

simply z.B. in a nProc testing:
Compile Mark Separation

nProc Test

    parameters a&,b&
    //sinnfrei
    mov eax,a&
    mov ebx,b&
    push eax
    mov b&,ebx
    pop ebx
    mov a&,ebx
    return a&

endproc
