Hi,

I am using EDK. For a microblaze, while doing program I need to take nth power of a number.

But when I do (n^m) then it gives me X-OR operation result.

How can I overcome this problem?

Please help me...!

In the C language, the caret (^) is the bitwise XOR operator and double-asterisk (**) is the power function.  So you need to write x**n to raise x to the nth power.

Hi Sandeep,

You could also use the pow(x, y) (double precision) or the powf(x, y) (single precision) functions.

Uh, that would be Fortran. There is now power operator in C, only the floating point functions mentioned before.

Hey thanks all.

I am able to solve the problem by using powf function and not (**).

As well increasing the onchip BRAM size from 16KB to 32KB.

Floating point powf function need some more memory space and hence was giving an error for Data2MEM execution.

Thanks to all ..!!
