IN the TEXT part of the problem the values display with 4-6 decimals, Likewise in the answer check. However, when we display the solution, the results display 15 digits, e.g.
B=7/52=0.134615384615385." role="presentation">B=7/52=0.134615384615385.
the code is
How do I get this display to limit the number of decimals?
The code is
$PAR
To find the particular solution, we know the form of the particular solution is the same as that of the driving function. In this case, it is a constant, \( v_p(t) = B \). We differentiate the particular solution as needed and substitute into the differential equation. Since \( \dot{v}_p(t) = \ddot{v}_p(t) = 0\), we have the equation, \( $c v_p(t) = $c B = $A.\) We solve for \( B \) to obtain \( B = $A/$c = $B.\)
$PAR
B=7/52=0.134615384615385." role="presentation">
If you see that many decimals, you are probably displaying a "pure" perl scalar real.
If you see something trimmed to about 6 decimals, you are probably seeing a MathObject Real.
My guess is that if you look closely at the two variables used in the two places, they are not actually the same thing. Or there is a reassignment of that variable in between.
Here is some example code:
$b = 7/52;
# $b is now a perl sclalar real with value 0.134615384615385...
# It will display as 0.134615384615385
$B = Compute(7/52);
# $B is a MathObject.
# Compute will recognize to make it a Real, as opposed to say a Formula.
# You could achieve essentially the same thing with:
# $B = Real(7/52);
# $B = Real("7/52");
# $B = Real($b);
# $B = Real("$b");
# $B = Compute("7/52");
# $B = Compute($b);
# $B = Compute("$b");
# although some of these would store a little extra information than others.
# While the information 0.134615384615385... is still stored within $B,
# the default display controls for MathObjects
# would only display this as 0.134615

great - very helpful and that dd the trick
