Yup, you can't change the value of a variable in XSLT once it's been bound.

It doesn't change the value, it creates a new text node with the translated value. if you do

  <xsl:value-of select="translate($field, ',', '.')" />
  <xsl:value-of select="$field" />

the latter value-of will evaluate to the original value.

You don't in XSLT.

They are equivalent, but the value of $field doesn't change. The xsl:value-of evaluates the string value of the new text node created by the translate function.
