IDENTICAL code gives different answers in two different scripts.
Here's the code:
property form_height : ((1.75 - 0.7) * 72) --=75.6
to findRound of num given numDecimals:n
set x to 10 ^ n
return (((num * x) + 0.5) div 1) / x
end findRound
set rounded_height to findRound of form_height given numDecimals:2
When run in a Script Editor window by itself, this gives the expected
result of 75.6 (apparently trailing zeroes are trimmed).
If you need consistency, here are some 'do shell script' calls.
Round: do shell script "tclsh <<< 'puts [expr round(" & form_height & ")]'" do shell script "tclsh <<< 'puts [expr ceil(" & form_height & ")]'" do shell script "tclsh <<< 'puts [expr floor(" & form_height & ")]'"
Specify a specific precision using standard 'printf' format specifications it:
do shell script "tclsh <<< 'puts [format %.2f " & form_height & "]'"
