Claim 17:
18. A method comprising:
performing ray tracing circuitry by a plurality of floating-point processing operations to detect intersection between a virtual ray defined by a ray direction and a test region, the floating-point processing operations operating to a given precision to generate an output floating-point value comprising a significand and an exponent;
for at least some of the plurality of floating-point circuitries, rounding using a predetermined directed rounding mode each denormal floating-point value generated during the floating-point processing operation so as to output a normal value, a denormal floating-point value being a floating-point value in which the significand comprises one or more leading zeroes; and
in at least some of the plurality of floating-point circuitries, the predetermined directed rounding mode is round-to-zero.
