Related Exp Example $x = Log(1000) ;returns 6.90775527898214 $y = Log10(1000) ;returns 3 ; user-defined function for common log Func Log10($x) Return Log($x) / Log(10) ;10 is the base EndFunc Function Reference Mod chia lấy phần dư. Mod ( value1, value2 ) Parameters value1 số bị chia value2 số chia Return Value Success: trả lại số Failure: trả lại -1. nếu lỗi chia cho 0. Remarks hàm có thể làm việc với cả số thực Related None. Example $n = 18 If mod($n, 2) = 0 Then MsgBox(0,"", $n & " is an even number.") Else MsgBox(0, "", $n & " is an odd number.") EndIf $x = mod(4, 7) ;$x == 4 because the divisor > dividend $y = mod(1, 3/4) ;$y == 0.25 because the divisor is a float Function Reference Random trả lại một số ngẫu nhiên. Random ( [Min [, Max [, Flag]]] ) Parameters Min giới hạn giá trị nhỏ nhất có thể đạt đc, mặc định = 0 Max giới hạn giá trị lớn nhất có thể đạt đc, mặc định = 1. Flag = 0 lấy số thực (mặc định) = 1 chỉ lấy số nguyên Return Value Success: số Failure: trả lại 0 và set @error=1 nếu tham số ko hợp lệ Remarks By default the Random function works with decimal/floating point numbers. If you want to only have integer/whole number results then set the Flag to 1. If only one argument is provided, then it is interpreted to be the Max. The result will be in the range of Min to Max INCLUSIVE when using integers (just short of Max when using floats). When using integers Max-Min must be less than 2^31. Comments based on the original source This function uses the Mersenne Twister random number generator, MT19937, written by Takuji Nishimura, Makoto Matsumoto, Shawn Cokus, Matthe Bellew and Isaku Wada. The Mersenne Twister is an algorithm for generating random numbers. It was designed with consideration of the flaws in various other generators. The period, 2 19937 -1, and the order of equidistribution, 623 dimensions, are far greater. The generator is also fast; it avoids multiplication and division, and it benefits from caches and pipelines.
