Numbers are strings. Bracmat supports rational numbers, including integers, using arbitrary-precision arithmetic. Pure imaginary numbers are formed using a factor <code>i</code> (or <code>-i</code>).

Bracmat also supports floating point numbers, but only in a sandboxed way. To increment 0.234E0 by 1:
<syntaxhighlight lang="bracmat">(new$(UFP,(=(s.val).!val+1)).go)$"0.234e0"</syntaxhighlight>
Output
<pre>1.2340000000000000E+00</pre>
<code>UFP</code> is a new (2023) object type that specializes in compiling and executing floating point operations. Bracmat code must be passed when a UFP object is created. This code has a more restricted grammar than Bracmat code in general. The passed code must be the definition of a function that can take one or more scalars or arrays as argument. In the example, this function is <code>(=(s.val).!val+1)</code>. The expression <code>(s.val)</code> says that the function takes a scalar and binds it to the local variable <code>val</code>. In the example, the function is defined, compiled, executed and destroyed in one go. This is not necessary; it is perfectly possible to use the compiled UFP object multiple times before destroying it.
