Claim 0:
1. Circuitry comprising:
ray tracing circuitry comprising a plurality of floating-point circuitries to perform floating-point processing operations to detect intersection between a virtual ray defined by a ray direction and a test region, the floating-point circuitries operating to a given precision to generate an output floating-point value comprising a significand and an exponent, wherein:
at least some of the plurality of floating-point circuitries are configured to round using a predetermined directed rounding mode each denormal floating-point value generated during the floating-point processing operations 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.
