FTOI	Floating point to integer conversion	FTOI
	Float TO Integer

[Syntax]

FTOI src, dest

[Operation]

dest = ( signed long ) src;

[Function]

-	This instruction converts the single-precision floating-point number stored in src into a signed longword (32-bit) integer and places the result in dest.

-	The result is always rounded towards 0, regardless of the setting of the RM[1:0] bits in the FPSW.

Z : The flag is set if the result of the operation is 0; otherwise it is cleared.

S : The flag is set if the sign bit (bit 31) of the result of the operation is 1; otherwise it is cleared.

CV : The flag is set if an invalid operation exception is generated; otherwise it is cleared.

CO : The value of the flag is always 0.

CZ : The value of the flag is always 0.

CU : The value of the flag is always 0.

CX : The flag is set if an inexact exception is generated; otherwise it is cleared.

CE : The flag is set if an unimplemented processing exception is generated; otherwise it is cleared.

FV : The flag is set if an invalid operation exception is generated; otherwise it does not change.

FX : The flag is set if an inexact exception is generated; otherwise it does not change.

Note	The FX and FV flags do not change if any of the exception enable bits EX and EV is 1. The S and Z flags do not change when an exception is generated.
