I'd say that it's a bug. A workaround (not a fix...) is to say
for i in 1..1 repeat print(sqrt(i) @ Complex Float)
It is quite clear that Axioms behaviour will be the same for all operators
(defined in op.spad).
Tracing the call with
)set message bottom on
yields
for i in 1..3 repeat print((sin(i))::Complex Float)
Function Selection for sin
Arguments: PI
-> no appropriate sin found in PositiveInteger
-> no appropriate sin found in Integer
-> no appropriate sin found in PositiveInteger
-> no appropriate sin found in Integer
Modemaps from Associated Packages
no modemaps
Remaining General Modemaps
[1] D -> D from D if D has TRIGCAT
[2] FortranExpression(D1,D2,D3) -> FortranExpression(D1,D2,D3)
from FortranExpression(D1,D2,D3)
if D1: LIST SYMBOL and D2: LIST SYMBOL and D3 has FMTC
[1] signature: EXPR INT -> EXPR INT
implemented: slot $$ from EXPR INT
Function Selection for print
Arguments: COMPLEX FLOAT
-> no appropriate print found in Complex Float
-> no appropriate print found in Complex Float
Modemaps from Associated Packages
no modemaps
Remaining General Modemaps
[1] OutputForm -> Void from PrintPackage
[1] signature: OUTFORM -> VOID
implemented: slot (Void)(OutputForm) from PRINT
sin(1)
sin(2)
sin(3)
Type: Void
which looks quite strange: Axiom is looking for a function print with argument
of type Complex Float, but the thing it prints is not of this type...
