Abstract

An instruction to convert data from a source data type to a target data type is obtained. The source data type is selected from one or more source data types supported by the instruction, and the target data type is selected from one or more target data types supported by the instruction. Based on a selected data type of the source data type or the target data type, a determination is made of a rounding mode for use by the instruction. The rounding mode is implicitly set based on the selected data type; it is assigned to the selected data type. A conversion of the data from the source data type to the target data type is performed. The conversion includes performing a rounding operation using the rounding mode implicitly set. The performing the conversion provides a result in the target data type, which is written to a select location.
