26.6.9.2.2 Class template uniform_­real_­distribution [rand.dist.uni.real]

A uniform_­real_­distribution random number distribution produces random numbers x, , distributed according to the constant probability density function
[Note 1:
This implies that is undefined when a == b.

Preconditions: and .
Remarks: a and b correspond to the respective parameters of the distribution.
result_type a() const;
Returns: The value of the a parameter with which the object was constructed.
result_type b() const;
Returns: The value of the b parameter with which the object was constructed.
