[doc bug] precedence

[maxchen]

in "EViews 7 Users Guide I.pdf", (ver April 2, 2010) P132

Code: Select all

precedence order as follows (from highest precedence to lowest): [*]unary minus (-), unary plus (+) [*]exponentiation(^) [*]multiplication (*), division (/) [*]addition (+), subtraction (-)

Should be

Code: Select all

[*]exponentiation(^) [*]unary minus (-), unary plus (+) [*]multiplication (*), division (/) [*]addition (+), subtraction (-)

see the change log

Code: Select all

http://www.eviews.com/download/ev6download.html July, 2007 Changed the precedence of unary negative sign and raised to the power (^) in scalar operations to match that of series operations so that for example -3^2 = -9 instead of 9.

the following code is test on EViews 5.1 (ver 20071008) V6 and V7.1

Code: Select all

wfcreate u 8 genr a = -3^2 genr b = -a^2 genr x = (-3)^2 group ga a b x show ga

thus, the simple examples in the same page , "-1^2, evaluates to (–1)^2=1 since the unary minus is evaluated prior to the power operator." is not consistent with the new update (versions)

Thanks.

Hmm, at the same page, for logical operators, there should be "not, and, or". Say, " and or" --> "not and or". 3 logical operators
