floating point - multiplication R without float -

-

is there way multiplication float in serie sof 2 multiplications integers. need write function accepts input values such as

3.4556546e-8

1.3

0.134435

instead of doing 100*0.134435 100/1000000 , multiply

134435

the function should output give 1000000 , 134435 - needed because need work large numbers in big integers , mutipliying anythign except intgers doent work

apparently want arbitrary precision arithmetics. don't need reinvent wheel.

library(gmp) x <- as.bigq(0.134435) 100 * x #big rational ('bigq') : #  [1] 121088283181110525/9007199254740992

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens ...
