Factor of 2?

Hi - is is possible that this equation should be modified as noted below?

// return mean + variance * cos( 2 * M_PI * R1) * sqrt(-log(R2));
return mean + variance * cos( 2 * M_PI * R1) * sqrt(-2*log(R2));

This appears to be the Box-Muller Transformation, and thus I think there needs to be a 2 inside the sqrt.
thx

Locate the Gaussian-generation code containing the displayed return equation and read the surrounding implementation. Verify the formula against the Box–Muller transformation, then run the repository's available tests or examples and confirm the generated values still behave as expected.
