storedIntegerToDouble

Convert stored integer value of fi object to built-in double value

Syntax

d = storedIntegerToDouble(a)

Description

d = storedIntegerToDouble(a) converts the stored integer value of fi object, a, to a double-precision floating-point value, d.

If the input word length is greater than 52 bits, a quantization error may occur. Inf is returned if the stored integer value of the input fi object is outside the representable range of built-in double values.

Convert Stored Integer Value of `fi` Object to Double-Precision Value

Open Live Script

Convert the stored integer of a fi value to a double-precision value. Use the class function to verify that the stored integer is a double-precision value.

a = fi(pi,1,16,12)

a = 
    3.1416

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 12

d = storedIntegerToDouble(a)

d = 
12868

dtype = class(d)

dtype = 
'double'
