thousands;ones

[Joe G]

if i write "movlw .100" equals the decimal of 100. would thousands be "1.00" , tens
be ".01" and ones be ".001" ?

No the "." just signifies what follows is in decimal (integer).

 

[Joe G]

i just put them there for the wording, i should of know that in coding they may chg what you ment... i should of wrote

movlw .100

my oops, thanks

Since W is only a byte register you can only use .0 - .255 or 0x00 - 0xFF

ugh, i got it now, you used the quotes too, roll. i'm a little slow today.

 

[Joe G]

)then, how would i write onethousand ,if i wanted to subtract 1000 from my pulse reading ( im working on a rpm 7seg display)?

 

[Joe G]

also i should of wrote subwf , i'd be subtracting from a file that holds my result

You need a math library or figure out how to do multi byte math. You might want to look into a high level language with math functions like C or BASIC.
