(optional) random number generator to use; if not specified, defaults to rndGen
Floating-point random variate of type T drawn from the uniform distribution across the half-open interval [0, 1).
import std.math.operations : feqrel; auto rnd = MinstdRand0(42); // Generate random numbers in the range in the range [0, 1) auto u1 = uniform01(rnd); assert(u1 >= 0 && u1 < 1); auto u2 = rnd.uniform01!float; assert(u2 >= 0 && u2 < 1); // Confirm that the random values with the initial seed 42 are 0.000328707 and 0.524587 assert(u1.feqrel(0.000328707) > 20); assert(u2.feqrel(0.524587) > 20);
Generates a uniformly-distributed floating point number of type T in the range [0, 1). If no random number generator is specified, the default RNG rndGen will be used as the source of randomness.
uniform01 offers a faster generation of random variates than the equivalent uniform!"[$(RPAREN)"(0.0, 1.0) and so may be preferred for some applications.
