Symantic type error on expression Mar 28th, 2007, 3:28pm   Hi, have the following error on my code. "Symantic Error: The type of this expression, "float", is not an integral type." Code: int D = numValues; float d = 0.0; for (int i=0; i < D; i++) { d = d + 1.0/(lambda[i]^2.0); } d = 1/sqrt(d); on the line Code: d = d + 1.0/(lambda[i]^2.0); . Any help would be appreciated. I have tried changing d to a double but still get the same error. Cheers.

Worked it out before your post, trouble was the error wasnt very helpful until i compiled the same code in a java editor which pointed me to the ^, but thanks for putting up with noobish questions.
