On your website for the mt_srand (in english and in french), you have writen in the "description" section :
void mt_srand ([ int $seed ] )

= I understand that the 'seed' has to be an int value

In the "parameters" section :
seed : an optional seed value (english version)
seed : une valeur d'initialisation aléatoire (french version)

= no explanation about what is the "value" or "valeur"

And in the "examples" section "Example #1 mt_srand() example" :

the make_seed function returns a float !

What should be the "value" ? A (int) or a (float) ?
It will be great if the 3 sections "description", "parameters" and "examples" were coherent

Best regards

Indeed, the example doesn't make sense.

mt_srand() expects an integer value[1], so basically anything
between PHP_INT_MIN and PHP_INT_MAX. However, this value will be
passed to php_mt_srand() which expects an unsigned integer, so
negative values will overflow, what doesn't appear to be a
particular issue in this case.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
