Syntax
cvtgd $s_reg, $d_reg
cvtgd $d_reg/$s_reg
Description
Convert G_floating to D_floating converts the G_floating contents of $s_reg to the D_floating precision, rounds according to the rounding mode, and places the result in $d_reg. If an overflow occurs, an unpredictable value is stored in $d_reg and a floating-point trap occurs.
