1e38 limit?
type: item
description: hello, i read float numbers from a text file, and eventually i need to multiply them by large numbers ~1e40. 'result' is the array that i read from the text file, and 'chi' is the array i'm analysing. i extract it with: chi = double(reform(result[3,*])) and then i do something like: chi = chi * 1e40 but the routine apparently enters into an infinite loop, lots of CPU, RAM and HD usage, and i end up having to kill the process after a while. trial-and-error showed me that as long as i keep the multiplicative factor <= 1e38, everything runs smoothly. i tried even a stupid: chi = chi * 1e38 chi = chi * 1e2 but the routine still gets crazy with that. what is going on? how can i work it around? many thanks, paula
