what's wrong?

[Came]

i am new to this

 

this is problem

 

 

Command: (+ .618 1)

; error: misplaced dot on input

 

Command: (1/(+0.618 1))

; error: bad function: 0.618

 

Command: (1/(+5 1))

; error: bad function: 5

 

am trying to type that simple command and i cep getting error

 

 

 

 

am learning basic

My guess is that there is no spaces between the functions and the numbers.

(+ 0.618 1) ;notice the zero in front of the dot
(/ 1 (+ 0.618 1)); almost always a function after an opening parenthesis

thanks

 

nervous i think it s first time, i will post in near future some similar

 

question

 

 

just started to reading and practicing

 

i got

 

Command: (/ 1 (+ 0.618 1))

0.618047

 

Command: (+ 0.618 1)

1.618

 

i was in that problem about 30 min

 

 

 

works

No problem Came,

 

I'm sure most of us have been there.

 

1 more point I would also stress is that when specifying the numbers, specify them as reals and not integers (particularly when doing division), as, otherwise you will get weird answers like say:

 

(/ 1 4) = 0

 

Whereas

 

(/ 1. 4.) = 0.25

 

and

 

(/ 1.0 4.0) = 0.25

 

Hope this helps!
