Question

I want to convert double precision numbers to decimal .

for example I have 23.43, the double value would be (using matlab) : 174 71 255 122 20 110 55 64
now having this how can I write a java program that gives me 23.43 ?

and here is the calculation of double precision in matlab :

MATLAB constructs the double data type according to IEEE Standard 754 for double precision. Any value stored as a double requires 64 bits, formatted as shown in the table below:

Bits
Usage

63
Sign (0 = positive, 1 = negative)

62 to 52
Exponent, biased by 1023

51 to 0
Fraction f of the number 1.f

Answer 1

long l = Double.doubleToLongBits(double);
double d = Double.longBitsToDouble(long);
