Code	Result with sandbox template	Result with main template	Note
{{Random number}}	Template:Random number/sandbox	4	default parameters (results range is 0..99)
{{Random number|100|181|67}}	Template:Random number/sandbox (ok)	4 (ok)	should be same as above (the default seed depends on current day of year, the default prime is 67)
{{Random number|10000}}	Template:Random number/sandbox	6904	new parameters (results range in 0..9999)
{{Random number|10000|181|67}}	Template:Random number/sandbox (ok)	6904 (ok)	Should be same as above
{{Random number|10000|181|61}}	Template:Random number/sandbox	9868	(use another prime) this and others should all be different
{{Random number|10000|6}}	Template:Random number/sandbox	5179	(varying the seed) note that the sequence is linear but the distance only depends on the value of the default prime (67)
{{Random number|10000|5}}	Template:Random number/sandbox	5112

{{Random number|10000|6|2}}	Template:Random number/sandbox	8662	(varying the seed) with a small prime (2) should still get distinct values in the linear sequence

Sandbox notes

This version uses fmod builtin operator (no longer need of Template:Mod) and the largest Mersenne prime (2³¹−1) that fits in 32 bits.

This Mersenne prime is chosen to offer equal distribution when reducing the number of digits (better than bitmasking by an exact power of 2).

The next Mersenne prime (2⁶¹−1) is too large to fit in 64-bit integers for computing products by reasonable primes (we could only use 2, 3, 5 or 7), or even just in the 52 bits of precision of a double float (used by #expr).
