We just discovered another very annoying bug similar to this one: https://help.zoho.com/portal/en/community/topic/bug-report-whole-number-field-prints-as-currency (which by the way, to this date no one has acknowledged or bother to confirm in Zoho).
When you use an email template to send mail to a Potential, the email displays all DECIMAL fields as currency !
In other words, what should display in the email as "5.02" displays instead as "$5.02"
In our communications with our customers it's easy to sound ridiculous with this type of mangling in the display/formatting of the fields.
Hope someone checks and corrects this soon.
