Print Precision ⎕PP

⎕PP is the number of significant digits in the display of numeric output.

⎕PP is an implicit argument of:

  • monadic functions: ⍕
  • system functions: ⎕FMT
  • other syntax: ⎕ and ⍞ output

⎕PP is ignored for the display of integers.

⎕PP may be assigned any integer value in the range 1 to 34. ⎕PP has Namespace scope.

Examples


      ⎕PP←10

      ÷3 6
0.3333333333 0.1666666667

      ⎕PP←3

      ÷3 6
0.333 0.167

If ⎕PP is set to a value ≥17 (when ⎕FR is 645) or 34 (when ⎕FR is 1287), floating-point numbers may be converted between binary and character representation without loss of precision. Then, if ⎕CT is 0 (to ensure exact comparison), for any floating-point number N the expression N=⍎⍕N is true.

⎕PP does not apply in the following contexts:
