Indeed it is not a good example because the division by 0 can not be trapped by the FreeBASIC error handling.
Otherwise, you can refer to Error Handling in the Programmer's Guide.

The exponent-part consists of from three to five ^ that must immediately follow the decimal-part: ^^^ for the exponent part on one digit (after the sign): E+/-# ^^^^ for the exponent part on two digits (after the sign): E+/-## ^^^^^ for the exponent part on three digits (after the sign): E+/-### I c...

This quickly accumulates:
10 km per afternoon (approximately 3 hours of walking in uneven terrain) * 6 days a week (Sunday rest) * 6 weeks = 360 km.

I lived 4 years in Le Havre in the 70s!

I am 69 years old and I do not feel at all old. It is true that I am lucky to be in good health and good physical condition. Next weekend, I'm going on vacation as usual in the mountains where I hike a little each afternoon, so that out of the total vacation I have covered more than 300 km on foot, ...

Blocked again?

Since Windows version 1809, do not install the next version immediately does not prevent to continue to apply the updates of the previous version, and this for many months (about 9 months) before Windows Update alerts on the need to install the new version.

I see for a few days that this 2004 version is offered to me optionally in the Windows Update menu, but as usual for new versions, I wait a few months for stabilization before applying it (probably this autumn).

I'm talking about this line of code: if f=0 then total+=sqr(L) else total+=L in the function 'distance(points() As pt,f as long=0) As double' . He then compares (in https://www.freebasic.net/forum/viewtopic.php?p=273613#p273613) the results ( 'total' ) obtaine...

@dodicat, We can not compare: SUMi(Xi^2) with: SUMi(SQR(Xi^2)) because the SQR function induces a non-linearity in the sum. Examples where that fails: X1 = 1, X2 = 6 SUMi(Xi^2) = 37 SUMi(SQR(Xi^2)) = 7 X1 = 3, X2 = 5 SUMi(Xi^2) = 34 SUMi(SQ...

It could be better to also try with:
DIM SHARED AS INTEGER hWave

Do you compile in 32-bit or 64-bit?

Thank you.
Done.

@Admin,
can you remove this duplicate (with viewtopic.php?f=8&t=28659) ?
