FPU problem

FPU problem

FPU problem

I have this code using masm32:

  FLD Temp         ;load Temp to FP stack
PrintDec Temp      ;DEBUGGER, print value of Temp  (256)
  FLD Cr           ;load Cr to FP stack                          
  FST Temp         ;store ST(0) to Temp
PrintDec Temp                                                                 ;DEBUGGER, print value of Temp  (-2)
  FMUL          ;ST(0) x ST(1)   
  FST Temp         ;store ST(0) to Temp
PrintDec Temp      ;DEBUGGER, print value of Temp  (-512)

The debug window displays this:

Temp = 256
Temp = -2
Temp = -2

I expected the last Temp to be -512, but it is -2.  Where am I going wrong?

RE: FPU problem
