Key
uniform
Headline
whether all elements of a list are the same class
Usage
uniform L
Inputs
L:List
Outputs
:Boolean
whether all elements of {\tt L} are of the same @TO class@
Description
Example
uniform {2, 5, 0}
uniform {2*0.5, 5*0.5, 0/2}
Text
The second list is not uniform because 0/2 is represented as a rational
number (of class @TO QQ@), while 2*0.5 and 5*0.5 are represented as real
numbers (of class @TO RR@).
Example
uniform {hi, "hello"}
uniform {"hi", "hello"}
R = QQ[x,y,z];
uniform {x^2*y*z, 5*y, 12/7}
uniform {x^2*y*z, 5*y, (12/7)_R}
S = ZZ[t];
uniform {monomialIdeal(x), monomialIdeal(t)}
uniform {monomialIdeal(t), ideal(t)}
uniform {S/monomialIdeal(t), S/ideal(t)}
