Syntax
divs $s_reg1, $s_reg2, $d_reg
divs $d_reg/$s_reg1, $s_reg2
Description
Divide S_floating computes the quotient of two values. These instructions divide the contents of $s_reg1 or $d_reg by the contents of $s_reg2 and place the result in $d_reg. If the divisor is 0, an error is signaled if the divide-by-zero exception is enabled.
Qualifiers
The following table describes the qualifiers for the divs instructions:
