## ◆ DeDenormal() [1/2]

void AAX::DeDenormal | ( | double & | iValue | ) |
| inline

Clamps very small floating point values to zero.

On Pentiums and Pentium IIs the generation of denormal floats causes enormous performance losses. This routine removes denormals by clamping very small values to zero. The clamping threshold is very small, but is not the absolute minimum. If absolute minimum clamping is desired, use AAX::DeDenormalFine()

## ◆ FastTrunc2Int32() [1/2]

int32_t AAX::FastTrunc2Int32 | ( | double | iVal | ) |
| inline

Float to Int conversion with truncation.

Parameters

  [in] | iVal | Value to convert

Note
  This truncation is NOT identical to C style casting. Because the Intel (and I would assume PowerPC) processors use convergent rounding by default, exactly whole odd numbers will truncate down by 1.0 (e.g. 0.0->0, 1.0->0, 2.0->2, 3.0->2). Surprisingly, even with these limitations this fast float to int conversion is often very useful in practice, as long as one is aware of these issues.

Note
  This method produces lower quality random numbers (i.e. less random) than plain old GetInt32RPDF, but in many cases it should be plenty good.
