# Qbasic calculation

## Qbasic calculation

I've made this one program as shown below. This is originally from GW basic, i modified abit for the reason where i can match any gases i want as shown in line 508

doesn't calculate as it is supposed to. but this part i totally just copied from the originally GW basic program. can anybody tell me what is wrong with it? Thank tou very much

### RE: Qbasic calculation

The code you posted is difficult to read (GW Basic code is).  Can you specify the calculation you are trying to do?  It will REALLY help us help you.

ouh... ahaha i figured that much, i mean difficult... anyway, before i ask more about the calculation what does # and ! mean???

### RE: Qbasic calculation

type definition

# = double percision (15 decimals)
Pi# = 3.141592653589793

! = single percision (7 decimals)
Pi! = 3.1415926

### RE: Qbasic calculation

Have you tried running the unaltered code?

### RE: Qbasic calculation

(OP)
yea ive tried but it keeps pn saying subscript out of range... btw i got this working already =D apparently i missed something...

anyway if u could help, what does lsd stand for here? is it just a variable or is it something specified such as least significant digit???
