Title: Issue with version 0.2.1
Post by: Arnold on June 26, 2019, 02:43:22 PM

Hi Charles,

print val("+15") ", " val("-12") will output: 0, -12. Should this not be 15 ?

Aren't positive numbers assumed? I rarely see a + to indicate a positive number.

I'll update the RTLs (ascii_to_float) so that '+' is ignored at the start of a number string.

It will be treated like leading spaces:

Code: [Select]

  'SKIP LEADING WHITE SPACE ETC
  '
  (
    mov al,[rcx]
    cmp al,0
    jz numnok 'end of string (error)
    (
     cmp al,43 'ignore '+'
     jnz exit
     mov al,32
    )
    cmp al,32
    jg exit 'start of word
    inc rcx
    repeat
  )
