Function std.random.uniform01

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!"[)"(0.0, 1.0) and so may be preferred for some applications.

Prototypes

T uniform01(T)()
if (isFloatingPoint!T);

T uniform01(T, UniformRNG)(
  UniformRNG rng
)
if (isFloatingPoint!T && isUniformRNG!UniformRNG);

Parameters

NameDescription
rng (optional) random number generator to use; if not specified, defaults to rndGen

Returns

Floating-point random variate of type T drawn from the uniform distribution across the half-open interval [0, 1).
