dear all:
in OpenVG spec. page 8(page 18 in PDF reader)
" ...at least 16 bits mantissa, and 6 bits for exponent....."

but in OpenVG page 9 (page 19 in PDF reader)
".. all implement must define VG_MAX_FLOAT to be at least 10^10..."

the precision s6.16 can not represent 10^10 correctly.....
so strange.
