\(\text{TRNGU}\)

You can use the \(\text{TRNGU}\) function to obtain a cryptographically secure random number in a uniform distribution.

You can use the \trngu backslash command to insert this function.

The following variants of this function are available:

• \(\text{integer } \text{TRNGU} \left ( \text{<any value>} \right )\)

The \(\text{TRNGU}\) function requires an arbitrary parameter that will be ignored.

The function returns a cryptographically secure random real number over the range [0, 1].

The \(\text{TRNGU}\) function uses the operating system’s cryptographic source of entropy. Note that the OS cyptographic entropy sources may be slow due to the underlying algorithms and available entropy.

\[a = \text{TRNGU } 0 \;\;\;\;\; \text{a = 0.8583003159825183248}\]
