PowerCalc 4.2E is the most powerful and flexible calculator in the
world. It meets the simplest-to-the-most-complex calculation demands
beautifully. It has flexible Expression support; scientific functions
(eg, sin, cos, tan, asin, acos, atan, atan2, exp, ln, log, pow, sqrt);
logging capability; screen print; etc. This one-of-the-kind,
think-out-of-the-box calculator can access expressions from files or
from the web, can save the log to a file, and much more.
PowerCalc 4.2E grows as you grow. You are invited to try this demo
version. While the demo version is fully-functional, it is limited to
support ONLY 10 calculations.
NOTE: PowerCalc 4.2E requires Internet Explorer 5.5 or later. Supported
platforms include Win 2000, Win XP, and later.
PS: PowerCalc 4.2E can use Active-X or OLE Automation.
You can use it to drive PowerBuilder OLE Automation.
For example,
assuming that you have user object (user) containing a public method
named user_i, then you can invoke it as:
var pb_i = new ActiveXObject ("PowerBuilder.Application.9");
pb_i.LibraryList = "c:\\vt\\bin\\user.pbd";
var user_i = pb_i.createobject ("user");
user_i.alert (pb_i.LibraryList);

| Yesterday, I had a business requirement to do 39 time calculations and
verification. For example, what is the result of:
"12:30:25" + 1250 seconds.
Using PowerCalc 4.2E I quickly wrote these two functions, and use them
to solve the problem.
/* Example: sec2time (123); */
function window.sec2time (n) {
sec = n %60; if (sec < 10) sec = "0" + sec;
hr = floor (n / 3600);
remSec = n - (3600 * hr);
if (hr < 10) hr = "0" + hr;
min = floor (remSec / 60);
if (min < 10) min = "0" + min;
return hr + ":" + min + ":" + sec;
}
/* Example: time2sec ("12:20:00"); */
function window.t2s (txt) {
arr = txt.split (":")
return (arr [0] * 3600) + (arr [1] * 60) + (arr [2] - 0);
}
//Usage:
//a = time2sec ("30:00:01") + time2sec ("00:10:10")
//sec2time (a)

| Save your time use Powerbuilder (6.5)
Time lt_time
lt_time = RelativeTime(12:30:25, 1250)
