How to get the decimal values using solve in MATLAB

So I am using solve in MATLAB to solve an inequation in MATLAB, to find the syms trough_rot_speed, here are the code
syms trough_rot_speed;
assume(trough_rot_speed,'positive')
A_equation = (sind(Alpha_deg-Beta_deg)/cosd(Beta_deg))*((a*trough_rot_speed^2)/9.8);
solution = solve( sqrt(pi^2+1)> A_equation> 1.15,trough_rot_speed,'ReturnConditions', true);
All the values are known except trough_rot_speed, I access the results by the following code
solution.conditions
But I get the value in fraction, like this:
How do I get it in decimal values, for example: x < 203.442....

Chaining relative comparisons does not work for numeric values, and does not work reliably for solve(). The only place it works reliably is piecewise(). You should rewrite as two conditions joined with &
