display - set and/or return decimal digits for displaying numbers
SYNOPSIS
display([d])
TYPES
d integer >= 0
return integer
DESCRIPTION
When given an argument, this function sets the maximum number of
digits after the decimal point to be printed in real or exponential
mode in normal unformatted printing (print, strprint, fprint) or in
formatted printing (printf, strprintf, fprintf) when precision is
not specified. The return value is the previous display digit value.
When given no arguments, this function returns the current
display digit value.
The builtin function:
display(d)
display()
is an alias for:
config("display", d)
config("display")
The display digit value does not change the stored value of a number.
It only changes how a stored value is displayed.
Where rounding is necessary to display up to d decimal places,
the type of rounding to be used is controlled by config("outround").
EXAMPLE
; print display(), 2/3
20 ~0.66666666666666666667
; print display(40), 2/3
20 ~0.6666666666666666666666666666666666666667
; print display(5), 2/3
