Hello Dimitrios!
The C28x plus floating-point (C28x+FPU) processor extends the capabilities of the C28x fixed-point CPU
by adding registers and instructions to support IEEE single-precision floating point operations. For more details you can refer to this RG (Please visit the site to view this file) & (Please visit the site to view this file). But it takes you time that you can spend on learning IQMath, because your DSP hasn't FPU. I would recommend you this link also http://processors.wiki.ti.com/index.php/IQmath_Library_for_C28x.

I did briefly try using IQMath and I was getting some compile or build errors that didnt make sense to me.

I suspect there were some issues of including IQMath to your project (for example http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/267829/937337.aspx#937337).
