Above documentation provides the following example:
Random gen(unpredictableSeed);
// Generate an integer in [0, 1023]
auto a = uniform(0, 1024, gen);
// Generate a float in [0, 1)
auto a = uniform(0.0f, 1.0f, gen);
Which, when complied, produces the following errors:
C:\Users\Andrew\code>dmd eds32
eds32.d(9): Error: function std.random.unpredictableSeed is used as a type
eds32.d(9): Error: cannot have parameter of type void
eds32.d(10): Error: function learn.eds32.randNum.gen (void) does not
match parameter types ()
eds32.d(10): Error: expected 1 function arguments, not 0
eds32.d(10): Error: template std.random.uniform(immutable(char)[]
boundaries = "[)",T1,T2,UniformRandomNumberGenerator) if
(is(CommonType!(T1,UniformRandomNumberGenerator) == void) &&
!is(CommonType!(T1,T2) == void)) does not match any function template
declaration
eds32.d(10): Error: template std.random.uniform(immutable(char)[]
boundaries = "[)",T1,T2,UniformRandomNumberGenerator) if
(is(CommonType!(T1,UniformRandomNumberGenerator) == void) &&
!is(CommonType!(T1,T2) == void)) cannot deduce template function from
argument types !()(int,int,MersenneTwisterEngine!(uint,32,624,397,
31,-1727483681u,11,7,-1658038656u,15,-272236544u,18))
Suggest that the first line of the example be changed to:
auto gen = Random(unpredictableSeed);
Or that a correctly working example be provided.
