Mathcad 15 returns a "This value must be a function, but has the form: Unitless" error with any type of argument I try calculating the real component of. I am using Mathcad 15 and I have units turned off. The "Im()" command works fine though. I am trying to compute the real part of a function's values ( Re(func(f))) ) but I continually get this error. As a sanity check I tried it using real and complex numbers but it does the same thing (however Im does not). As if that weren't weird enough, the "Re()" command works fine in another worksheet and I can have both open simultaneously.
