why can't i get sqrt of a raise into a float ?

[Lorentzos Roussos]

i have this :

float max_distance=MathSqrt((float)MathPow(((float)px_per_side+1),2.0)*2.0);  

and it raises this error :

but it accepts it like this :

float max_distance=0.0;
//float max_distance=MathSqrt((float)MathPow(((float)px_per_side+1),2.0)*2.0);  
double _mdd=MathSqrt(MathPow(((double)px_per_side+1),2.0)*2);
max_distance=(float)_mdd; 

what am i doing wrong ?

   It doesn't know whether 2.0 is a float or a double. You have MathSqrt( float, 2.0 ).
   

2. Your code	((double)px_per_side+1)
   Simplified	double(px_per_side+1)

ow it accepted this

float max_distance=(float)MathSqrt(MathPow(((float)px_per_side+1),(float)2.0)*2.0); 

thank you
