**Versioned name**: *Convert-1*
**Category**: type conversion
**Category**: *Type conversion*
**Short description**: *Convert* operation performs element-wise conversion on a given input tensor to a type specified in the *destination_type* attribute.
**Detailed description**
Conversion from one supported type to another supported type is always allowed. User must be aware of precision loss and value change caused by range difference between two types. For example, a 32-bit float `3.141592` may be round to a 32-bit int `3`. The result of unsupported conversions is undefined, e.g. convertion of negative signed integer value to any unsigned integer type.
