Integer Portion of a Number
To extract and display the integer portion of a number, execute INT (integer). For example, to extract only the integer portion of the number 123.4567:
Keystrokes Display    
123.4567
  123.4567 _    
   
XEQ 
  XEQ _ _    
   
ALPHA INT ALPHA 
  123.0000    
  Only the integer portion of the number remains.
When INT is executed, the fractional portion of the number is lost. The entire number, of course is preserved in the LAST X register.
Fractional Portion of a Number
To extract and display only the fractional portion of a number, execute FRC (fraction). For example, to extract only the fractional portion of the number 123.4567 used above:
Keystrokes Display    
g LASTX 
  123.4567    
  Summons the number from LAST X.
XEQ 
  XEQ _ _    
   
ALPHA FRC ALPHA 
  0.4567    
  Only the fractional portion of the number is displayed.
When FRC is executed, the integer portion of the number is lost. The entire number is again preserved in the LAST X register.
The Modulo Function (Remainder)
Executing MOD (modulo) performs y mod x (the equation is y – [<y/x>×x], where <> denotes the largest integer less than or equal to the indicated result), which divides y by x and gives the remainder of the division. So, when you place numbers in the X- and
