Values for Borland floating-point shortcut subcode:
Subcode		Function
 DCh	load 8086 stack with 8087 registers; overwrites the 10*N bytes at the
	  top of the stack prior to the INT 3E with the 8087 register contents
 DEh	load 8087 registers from top of 8086 stack; ST0 is furthest from top
	  of 8086 stack
 E0h	round TOS and R1 to single precision, compare, pop twice
	  returns AX=8087 status word, FLAGS=8087 condition bits
 E2h	round TOS and R1 to double precision, compare, pop twice
	  returns AX=8087 status word, FLAGS=8087 condition bits
	Note: buggy in TPas5.5, because it sets the 8087 precision control
	  field to the undocumented value 01h; this results in actually
	  rounding to single precision
 E4h	compare TOS/R1 with two POP's
	  returns FLAGS=8087 condition bits
 E6h	compare TOS/R1 with POP
	  returns FLAGS=8087 condition bits
 E8h	FTST (check TOS value)
	  returns FLAGS=8087 condition bits
 EAh	FXAM (check TOS value)
	  returns AX=8087 status word
 ECh	sine(ST0)
 EEh	cosine(ST0)
 F0h	tangent(ST0)
 F2h	arctangent(ST0)
 F4h	ST0 = ln(ST0)
 F6h	ST0 = log2(ST0)
 F8h	ST0 = log10(ST0)
 FAh	ST0 = e**ST0
 FCh	ST0 = 2**ST0
 FEh	ST0 = 10**ST0
