Floor - Learn To Code - PlayBASIC Documentation

Floor

Result = Floor(Value#)

Parameters:

Value# = The value you wish to floor

Returns:

Result = The truncated integer

      The Floor function returns a floating-point value representing the largest integer that is less than or equal to Value#.

      Functions like floor and int are useful when we don't want PlayBASIC to perform any rounding operations when moving the result of a floating point expression to an integer variable/array.

FACTS:

     * Int and Floor are functionality the same.

Mini Tutorial:

; set up a for not loop
  For lp=0 To 100 Step 10

   ; make V# equal to the loop counter divided by 100
     v#=lp/100.0
     Print "   V#="+Str$(V#)

   ; display V#  trancated by INT()
     Print "  Int:"+Str$(Int(V#))

   ; display V#  trancated by FLOOR()
     Print "Floor:"+Str$(Floor(V#))

  Next

; Display the Screen and wait for the user to press a key
  Sync
  WaitKey

This example would output.
