Hello!
I have a problem with bigfloat.
Anyone knows what i'm doing wrong?
Here's a snippet that shows the error
/// snippet
package require math::bigfloat
set content {8373;0;
8374;-6.9573623405856546;

8380;-6.9401076839889493;
8381;-6.9250138062697619;}
foreach line $content {
set number [math::bigfloat::fromstr [lindex [split $line ";"] 1] 20]
puts [math::bigfloat::tostr -nosci [math::bigfloat::mul $number $number]]
}

Exactly what the error says - you cannot specify the second arg (20) if the first arg is an integer
(wits) 52 % math::bigfloat::fromstr 0 10
F 0 -51 32768
/Ashok
(wits) 52 % math::bigfloat::fromstr 0 10
second argument not allowed with an integer
(wits) 53 % math::bigfloat::fromstr 0.0 10

Sure... but why ? A bigfloat being an interval [x-d,x+d], what's wrong

with x being integer dans d being 1e-10 ?

The short answer is: because.
The behaviour is actually documented.
The longer answer: it is a limitation in the current implementation, but
that could be changed. Could the OP register a change request in the Tcllib
project?
