1. Maths Functions
I have been looking for maths functions equivalent to the Basic
Round(x,no of places)
RoundUp
RoundDown
I didn't see them on the web site. Did I miss them or will I write my
own?

Hi Chris,
try these....
function RoundDown(atom a)
return floor(a)
end function
function RoundUp(atom a)
if integer(a) then
return a
else
return floor(a + 1)
end if
end function
function Round(atom a, integer places)
return floor(a * power(10, places) + 0.5) * power(10, -places)
end function

Derek:
A generalization and a slight improvement for your routines:
function RoundDown(object a)
return floor(a)
end function
function RoundUp(object a)
return -floor(-a)
end function
function Round(object a,integer places)
return floor(a*power(10,places)+0.5)*power(10,-places)
end function
Anyway, for routine Round, the results might not be accurate to 'places'
decimals, due to a small fuzz caused by binary versus decimal arithmetic, so
that if many figures are used for accounting purposes and added up, a
difference of a few cents might crop up. The only solution I know for this
problem is to work internally with cents instead of dollars and show the
results scaled.

See Refman2.html.
