fadd

fadd

Forms
fadd = 98 (0x62)

Stack
..., value1, value2 ..., result

Description
Both value1 and value2 must be of type float. The values are popped from the operand stack. The float result is value1 + value2. The result is pushed onto the operand stack.

The result of an fadd instruction is governed by the rules of IEEE arithmetic:

• If either value is NaN, the result is NaN.
• The sum of two infinities of opposite sign is NaN.
• The sum of two infinities of the same sign is the infinity of that sign.
• The sum of an infinity and any finite value is equal to the infinity.
• The sum of two zeroes of opposite sign is positive zero.
• The sum of two zeroes of the same sign is the zero of that sign.
• The sum of a zero and a nonzero finite value is equal to the nonzero value.
