if (std::abs(writeDataPtr[i] - (float(i) + 1.0f)) >= 0.02f)

Hi,

While compiling this on QNX it raises the error:

vktBindingStagesTests.cpp:445:57: error: call of overloaded 'abs(float)' is ambiguous

cmath header must be included to avoid this error, stdlib.h do not declare std::abs for float argument, cmath does.

Thank you!

std::abs is used twice in this module, next one is here:
