Override the default internal random number generator which is used for
|
|
Math.random() and some other internal call sites (currently, for example,
|
|
Array.prototype.sort()). The default random number generator has a very
|
|
low footprint but is not suitable for serious statistics algorithms or
|
|
cryptography. Overriding the random number generator may thus be useful
|
|
in some environments.
|
|
|
|
The macro gets a heap userdata argument and must provide an IEEE double
|
|
in the range [0,1[.
