FLOATU.X
Unsigned Integer to
FLOATU.X
Floating-Point Conversion
Description:
Convert the unsigned 32-bit integer located in the low portion of the operand D into a floating-point operand
and store the result in the operand D. The rounding precision is SEP.
Input Operand(s) Precision: 32-bit unsigned integer.
Output Operand Precision: SEP Floating-Point.
