TEXT to REAL..

Andrea:
Sorry, I know I have posted something similar few days ago..

but I can find a way to have the precision of 8 digit after the point.
I have this...

(setq a "2.06112265" )

I need to transform to REAL...

(read a)  = 2.06112
(atof a)  = 2.06112

How can I get the precision...in REAL... :oops:

note: my LUPREC variable is set to 8

Keith™:
The value is only displayed truncated ... the value is correct in the variable .. to test it, try this:


--- Code: ---(setq a "2.06112265")
!a
"2.06112265"
(setq b (distof a))
2.06112
!b
2.06112
(rtos b 2 8)
"2.06112265"

--- End code ---

thanks Keith..

but ho can I divide 1 by b ??

Keith™:

--- Code: ---(setq c (/ 1.0 (distof b)))
--- End code ---

Keith...

b is alraydy in REAL...I think you want write this..


--- Code: ---(setq c (/ 1.0 b))
--- End code ---

but the result is..
0.485172
and must be 0.485172486

also, if i write

--- Code: ---(rtos c 2 8)
--- End code ---
I obtain this result..."0.48517249"

not better..

I need to do this..

(/ 1 "2.06112265")
to have the exact result....

"0.485172486"
