{{tag>proxy function}}

====== clamp() ======
Used to limit the minimum/maximum value of an expression. Useful for things that need to stop at a given value.

===== Expression =====
<block box compact mono>
**clamp(input_value, lowest_value, highest_value)**
</block>

<block box compact>
<block mono>**input_value**</block>
The value that you want to limit, can be a function. A universal input that will work in most cases is <span code> start_value +/- timeex() * speed </span> </block>

<block box compact>
<block mono>**lowest_value**</block>
This is the lowest value that the function can output. This value is used instead of //input_value// when //input_value// is lower than //lowest_value//.
</block>

<block box compact>
<block mono>**highest_value**</block>
This is the highest value that the function can output. This value is used instead of //input_value// when //input_value// is higher than //highest_value//.
</block>

===== Examples =====
<block box>
==== Clamp ====
<span code>**clamp(5 + timeex(), 5, 10)**</span>

----

When shown, the proxy starts at 5 and increases over time thanks to <span code>timeex()</span>, <span code>clamp(input, %%min%%, %%max%%)</span> is used to limit the output so the value never goes above 10.

</block>

<block box>
==== Reverse Clamp ====
<span code>**clamp(10 - timeex(), 5, 10)**</span>

----

Same as above except the proxy starts at 10 and decreases over time thanks to <span code>timeex()</span>, <span code>clamp(input, %%min%%, %%max%%)</span> is used to limit the output so the value never goes below 5.
