When I finish the algebraic manipulations using the symbolic toolbox and start putting numbers into variables I always end up with clunky rational fractions such as
/ 890915281312783 x \
733 sin| ----------------- | i
\ 281474976710656 /
- ------------------------------
80000000
Is there a way to make this look like
9.1625e-006 sin(3.1652 x ) i ?
Thanks.

hi,
i have the same problem
how did you solve it?
when i write symbolic, i get big fractions and when they go to vpasolver, the calculation takes long so i want the fraction to be a number with 3 decimal digits.
