Bug#373622: kcalc: incorrect sine calculation

[Filip Spacek <filip@rapidmind.net>]

Package: kcalc
Version: 4:3.5.3-1
Severity: important

Calculating sin(18108.8) produces 0.946649 while the actual answer is 
0.61307. Check the compilation options for things like -ffast-math as
trig calculations for large inputs are expensive and are usually not 
done correctly if the compiler is instructed to generate fastest code
possible.
