precision 5530 2 in 1

Label: style blog color use for strong SP data Div We know that at present, the computer computing value has a high accuracy, but due to hardware restrictions, it is often unable to meet the actual production needs, so we can achieve high-precision computing through careful design of the program. Let's talk about this issue today. First, we should know that,Working principle of high-precision computing: Lik

High Precision Division: # Include High-Precision multiplication: # Include The last five hundred digits and total digits of msen (You do not need to determine whether it is a prime number) Formula: 2 ^ P-1 # Include

; k , NBSP; p ≤100). OutputIf It is more advantageous for Max does not register the accident and then output in the first line "Cash", otherwise output in The first line "Insurance" (including, if both options is equally disadvantageous). The second line output the amount for money in rubles, that's show how more advantageous your choice than the other one. The answer should is given with absolute or relative error not exceeding 10−6.Sample Input input Output

. Instead He gave you an array a1, A2, ..., Aksuch that In other words, n was multiplication of all elements of the given array. Because of precision difficulties, Barney asked you to tell him the answer as an irreducible fraction. In all words need to find it as a fraction p/q such that, where is the greatest common divisor. Since p and Q can be extremely large, you have need to find the remainders of dividing each of the them by 109 + 7. Please note

types, see the following section) Boolean This is the simplest type. Boolean represents the TRUE value, which can be TRUE or FALSE. When other types are converted to the boolean type, the following values are considered as FALSE: Boolean value FALSE Integer value 0 (0) Floating point value: 0.0 (0) Blank string and string "0" Array without member variables Objects without cells (applicable only to PHP 4) Special type NULL (including unset variables) All other values are considered to be TRUE (
