digits - Variable precision accuracy

Syntax

digits
digits(d)
d = digits

Description

digits specifies the number of significant decimal digits that Maple^® software uses to do variable precision arithmetic (VPA). The default value is 32 digits.

digits(d) sets the current VPA accuracy to d digits.

d = digits returns the current VPA accuracy.

Examples

If

z = 1.0e-16
x = 1.0e+2
digits(14)

then

y = vpa(x*z+1)

uses 14-digit decimal arithmetic and returns

y =
1.0000000000000

Whereas

digits(15)
y = vpa(x*z+1)

used 15-digit decimal arithmetic and returns

y =
1.00000000000001
