Comment #4 on issue 3852 by [email protected]: v8 module operation is
not compatible with ECMA SCRIPT
https://code.google.com/p/v8/issues/detail?id=3852
In v8's unit test(div-mod.js), (43 % 0.3) expected <0.10000000000000159> by
using fmod. But if modulo implemented being followed ECMA Script, found
<0.10000000000000142>. Actually precion issue is being existed... I don't
know why v8 use fmod that is not allowed in ECMA Script.
here is Modulo operation be followed by ECMA Script spec.
(ECMA Script says that r = n − (d * q) is formula of modulo operation)
vdiv(tempResult, left, right);
vcvt_s32_f64(tempResult.low(), tempResult); //for truncate division
vcvt_f64_s32(tempResult, tempResult.low());
vmls(left, tempResult, right);
