# TakeSmaller

Take values smaller than a threshold in a list or association

Contributed by: Wolfram Staff
 ResourceFunction["TakeSmaller"][list,val,n] gives the largest n elements in list that are smaller than val. ResourceFunction["TakeSmaller"][list→prop,val,n] gives the property prop for the n elements in list that are smaller than val. ResourceFunction["TakeSmaller"][val,n] represents an operator form of ResourceFunction["TakeSmaller"] that can be applied to an expression.

## Details and Options

ResourceFunction["TakeSmaller"] sorts by numerical magnitude.
ResourceFunction["TakeSmaller"] handles the same objects and properties as TakeSmallest.
ResourceFunction["TakeSmaller"] expects all objects to be comparable with one another.
ResourceFunction["TakeSmaller"][list,val,UpTo[n]] takes n elements, or as many as are available.
ResourceFunction["TakeSmaller"][assoc,val,n] gives an Association of length n by taking the n largest values that are smaller then val in assoc, preserving their keys.
ResourceFunction["TakeSmaller"][val,n][list] is equivalent to ResourceFunction["TakeSmaller"][list,val,n].

## Examples

### Basic Examples (5)

Take two numbers smaller than the specified value in a list:

 In[1]:=
 Out[1]=
 In[2]:=
 Out[2]=

Do the same using the operator form of TakeSmaller:

 In[3]:=
 Out[3]=
 In[4]:=
 Out[4]=

Take the largest two values smaller than the specified threshold in an Association:

 In[5]:=
 Out[5]=

Take the largest four numbers smaller than the specified value, or as many as are available:

 In[6]:=
 Out[6]=

Take all numbers with values under the threshold:

 In[7]:=
 Out[7]=

Take two values in a list of Quantity objects:

 In[8]:=
 Out[8]=

### Scope (3)

Get the two largest elements that are smaller than 23 in a list:

 In[9]:=
 Out[9]=

Get the positions of the two largest elements smaller than 3:

 In[10]:=
 In[11]:=
 Out[11]=

Get the elements along with their positions:

 In[12]:=
 Out[12]=

Let positions come first in the result:

 In[13]:=
 Out[13]=

Get associations containing the element and the position:

 In[14]:=
 Out[14]=

Get the two largest planets with the radii smaller than the Earth’s:

 In[15]:=
 Out[15]=
