Support › Meta Box Builder › Bug: Custom Field type Number allows characterResolved
The Custom Field type Number is allowing the character "e" to be inputted. Added via the Builder. See link.
The HTML5 input type number accepts the character e where the exponent is the number after the e or E, for example, 10e2 = 1000 but it isn't supported to save.
For more information, please follow some guides.
ahh.... thanks for the clarification.
