5.2 Early terminated iterative operation

 
example codes for comparing spl sql and python(23)

5.1 Simple iterative operations

Use the binary search to find the solution of lnx+2x-6=0 in the interval [0,3].

SPL

A B
1 1E-6
2 =y=1,1000.iterate((x=(~~(1)+~~(2))/2,y=ln(x)+2*x-6,if(y>0,[~~(1),x],[x,~~(2)])),[0,3],abs(y)<A1) /Binary search
3 =x /2.534919261932373

The ierate(x,a,c) is the iterative function with termination condition. In this function, c is the condition for terminating iteration.

Like common loop functions, we can define variables inside this function. The iteration termination condition set here is |lnx+2x-6|<1E-6.

SQL

SQL doesn’t provide a similar method.

Python

Python doesn’t provide a similar method.
