I have completed my analysis in BEM. The results gives me velocity potential in form of

37954305E-04 +1.58625295E-06 +2.10275811E-07 +....

I have real scattering values, imaginary and absolute scattering values in this form.

I am new to the method and from a different major, so my question may look silly.
In order to calculate the sound pressure, I have p=(rho)*(velocity potential) equation. (rho) is the density of the medium.

I do not know the format 0.0000E+00. What is it equal to? How may I convert it to calculate the equation?

Thanks. Best,
