Re: A83: two preesing questions
The command you are looking at is _formreal but it only converts an FP number
to a string. You need to get the register that you want and convert it into
a Floating Point number.
;Example 1 - displaying the value in register b
;This assumes you already have a value loaded into b
;and that you have already set the penrow and pencol to
;their correct positions. You can display any
;register you want, just makes sure to load it into a.
ld a,b ;the number needs to be put into a
call _setxxop1 ;move the value to op1
call _formreal ;make op1 a string
ld hl,op3 ;the string generated is put into op3
call _vputs ;display it
;Example 2 - displaying the value in register hl
;This assumes the same as the above
call _setxxxxop2 ;convert hl into an FP number
call _op2toop1 ;move op2 to op1
call _formreal ;make it a string
ld hl,op3 ;load the string
call _vputs ;display the string

string to _vputs. >>
