0.0156001 is close to 0.0156, and this number cannot be representated exactly
in binary:
>>> (0.0156).hex()
'0x1.ff2e48e8a71dep-7'
C code used by Python:
GetSystemTimeAdjustment(&timeAdjustment, &timeIncrement,
&isTimeAdjustmentDisabled);
info->resolution = timeIncrement * 1e-7;
(And yes, 0.0156001 is surprising, I also expected 1/64, 0.015625)
