Here is a list.

In[1]:=

This selects the numeric quantities from mm.

In[2]:=

Out[2]=

This selects the first .

In[3]:=

Out[3]=

This selects the ones that are less than .

In[4]:=

Out[4]=

Given a list of real numbers and a list of intervals, the function FindInterval returns a list of pairs. Each pair consists of a number and the interval containing that number. In this definition the intervals are closed on the left and open on the right.

In[5]:=

Here are three numbers.

In[6]:=

Here are two intervals.

In[7]:=

Since is contained in both and , FindInterval returns two pairs for .

In[8]:=

Out[8]=

The function allOddDigits gives all positive integers less than x with all odd digits. The in the inner Select terminates the test if an even digit is found.

In[9]:=

In[10]:=

Out[10]=

This gives the built-in functions that have the option Heads False.

In[11]:=

In[12]:=

Out[12]=

Here are the built-in functions with the option Heads True.

In[13]:=

Out[13]=

In[14]:=
