Even and Odd numbers

Post by marcoagpinto »

Hello!

How do I check if an integer is an even or odd number?

There are no functions to check.

What I did in the 1990s in Pascal was to use the MOD command.

PB too has a MOD command but the help doesn't explain the use of %.

Can someone help?

Thank you!

Code: Select all

For i=1 To 10
  n = Random(100)
  If n & 1
    Debug Str(n)+" is odd"
  Else
    Debug Str(n)+" is even"
  EndIf
Next
or

Code: Select all

For i=1 To 10
  n = Random(100)
  If n % 2
    Debug Str(n)+" is odd"
  Else
    Debug Str(n)+" is even"
  EndIf
Next
but & is much faster compared to %.

How about opening the help file, clicking at the "index" tab, then double-clicking at the 4th entry in the list?

an integer is odd if bit 0 is set as Wilbert's solution demonstrates.
