The round function implicitly uses + 0.5 before creating the file patch When I write this into the function round(0.499999999999999944, 0); with or without a constant PHP_ROUND_HALF_UP the result 1 is incorrect since the first digit is 4 and therefore not equal to 5 or greater Member Saki...
To achieve thesame effect as with casting to integer, you can: Usefloor()to round down positive integers, and; Useceil()to round up negative integers. Doing so wouldtruncatea floating point number towards zero. You can implement it, for example, like so: ...
Integer operations and conversions on numerical strings now respect scientific notation. This also includes the (int) cast operation, and the following functions: intval() (where the base is 10), settype(), decbin(), decoct(), and dechex(). 5.mt_rand 算法修复 mt_rand() will now default...
