+1  Q: 

in k_rem_pio2 file function is there any number which not hold carry!=0 for ih==2 case?

I'm working on application using the math computation. For my code I need to know how to cover all paths of code of libraries I'm using. The one of not covered yet is in k_rem_pio2 file. The kernel function have branch for ih==2 numbers and then ther is an if(carry!=0) -z= scalbn(one,q0);

my question is for what number the if condition is not met ... I assume that the only case would be number with iq[i] = 0 for all i < jz (I'm working with prec = 2), but which number can have iq[i] = 0?
