You're right. Wasn't seed changing but truly out of bound call.
Why do you need to generate uniform variate (0,1e38) ?
Curious about applications !

|
|This is seed changing? Since 'uniform' gives an array like this
|
|    >>> uniform(0,1e38)
|    array([ 5.15205248e+037])
|
|the call
|
|    >>> uniform(0,1e38)[1]
|
|is truly out of bound.
