Configuration, Task or Terminal
Limitations
Only 15 digits after the decimal point can be displayed. The statement,
printu "#.################";My_Var
Only prints 15 digits, and not 16 as specified by the format string. Only 16 digits before the decimal point are displayed. The statement:
printu "#.#";1e15
Is printed as
100000000000000.0
While
printu "#.#";1e16
Is printed as
1.0e16
print #1,"" emits \0 (zero character)
Examples
Specify a minimum number of characters to print by using the “#” sign and decimal point.
B = 33.344
PrintU "B is ##.##";B ‘prints B IS 33.34
PrintU "B is ##.####";B ‘prints B IS 33.3440
PrintU "B is ##.##^^^^";B ‘prints B IS 3.33e+01 (you must use exactly four ^s for this format to work)
Another example:
PrintU "The number is #";j1,j2
à The number is 1, The number is 2
Specifying the number of digits to print, prints data in tabular form since the number of places printed does not vary with the value of the number:
PrintU "Keep numbers to a fixed length with PrintUsing: ######" ; 100
