# accumpos

Add two fi objects or values

## Description

example

c = accumpos(a,b) adds a and b using the data type of a. b is cast into the data type of a. If a is a fi object, the default 'Floor' rounding method and default 'Wrap' overflow action are used. The fimath properties of a and b are ignored.

example

c = accumpos(a,b,RoundingMethod) adds a and b using the rounding method specified by RoundingMethod.

example

c = accumpos(a,b,RoundingMethod,OverflowAction) adds a and b using the rounding method specified by RoundingMethod and the overflow action specified by OverflowAction.

## Examples

This example shows how to add two fi numbers using accumpos.

Add a and b, where a and b are both fi numbers, using the default rounding method of 'Floor' and overflow action of 'Wrap'.

a = fi(pi,1,16,13);
b = fi(1.5,1,16,14);
-3.3584

Add two fi numbers using specified rounding and overflow action

Add a and b, where a and b are both fi numbers, using specified rounding method of 'Nearest' and overflow action of 'Saturate'.

a = fi(pi,1,16,13);
b = fi(1.5,1,16,14);
3.9999

Number to add. The data type of a is used to compute the output data type.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | fi

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | fi

Rounding method to use if a is a fi object.

Example: c = accumpos(a,b,'Ceiling')

Data Types: string
