Description
nsRandom is a NSIS-plugin created by Leon Zandman that can generate random numbers.
Usage
nsRandom is a plugin wrapper around Borland Delphi's Random() function. It can generate random numbers in two ways:
- Range-mode
- Float-mode
Range-mode
In this mode nsRandom generates a random number x in the following range: 0 ≤ x < Range, where Range is a positive number that has been pushed onto the stack. See the following example:
; Use random number from range: 0 <= Random < 100 ; Put range onto the stack Push "100" ; Get the random number nsRandom::GetRandom ; Take the generated number from the stack Pop $2
Float-mode
In this mode nsRandom generates a random number x in the range 0 ≤ x < 1. You can activate this mode by putting a negative value for Range onto the stack. See the following example:
; Put a negative range value onto the stack (=float-mode) Push "-1" ; Get the random number nsRandom::GetRandom ; Take the generated number from the stack Pop $2
Note
nsRandom was created after some discussion in this forum thread.
