title: Template file in yaml
body: <p><strong>Values.yaml</strong></p>
  
  <pre><code>cpulimit: 200m
  memlimit: 512M
  </code></pre>
  
  <p><strong>configmap.yaml</strong></p>
  
  <pre><code>mem_pool_size = {{ ((.Values.memlimit)) mul 0.8 }} --&gt; not working
  mem_pool_size = {{  .Values.memlimit mul 0.8 }} --&gt; not working
  mem_pool_size = {{ .Values.memlimit * 0.8 }} --&gt; not working
  mem_pool_size = {{ .Values.memlimit }} * 0.8 --&gt; not working
  mem_pool_size = {{ .Values.memlimit }} mul 0.8 --&gt; not working
  </code></pre>
  
  <p>Tried many ways but i dint got the exact solution.if user provides value of memlimit as 512M i should assign only 80 % ram so the value will be 410M. I am finding a way whether arithmetic operations are supported in helm templates. Is there any example for this.</p>
