By translating documentation, I've found some errors.  
SCALC  
1. There are errors in function names. e.g. error value #N/A is very often   
written as #NV, also in function name NA().   
Some Financial functions have old names in documentation (names are changed   
from 1.0.1 to 643c and some changes are not visible in help files).   
In example for function DB function name is written as DDB...  
2.  The angle 1.57 (Pi/2) returns a cosine of 0 radians. 
-This a little bit wrong. A result of sin, cos functions is unitless, the  
angle must be given in radians. Look at the rest of angle functions too. 
3. Documentation talks about function SCM_ADD - Smallest common multiple :) 
Here must be LCM_ADD - as Least common multiple  
4. MULTINOMIAL(F11:H11) returns 1260, if F11 to H11 contain the values 2, 3 
and  
4. This corresponds to the formula =(2!+3!+4!)/2!*3!*4!. 
Here the right formula must be: =(2+3+4)!/2!*3!*4! 
Also, here is the function name right, but in function list it is 'POLYNOMIAL' 
5. The formula: 
SERIESSUM(x;n;m;coefficients) = coefficients + coefficient2x(n+m) +  
coefficient3x(n+2m) +...+ coefficientix(n+(i-1)m) 
is wrong (and fuzzy) 
Right fomula is, I think: 
SERIESSUM(x;n;m;coefficients) = coefficient1*x^n + coefficient2*x^(n+m) +  
coefficient3*x^(n+2m) +...+ coefficienti*x^(n+(i-1)m) 
In this form, it works, at least :) 
6. in the same SERIESSUM, in example is used function FACTORIAL(xxx), that 
exists not. must be FACT(xxx)
