A floating-point number has four parts -- a sign, a mantissa, a radix, and an exponent. The sign is either a 1 or -1. The mantissa, always a positive number, holds the significant digits of the floating-point number. ... Float bits (sign exponent mantissa)

If the value is 3.25 then I want to get mantissa =.25, exponent = 3 ... To actually want the exponent and mantissa you can convert it into the IEEE 754 representation and extract the bits like this: ... Where n is the number to get the real mantissa/exponent:

long mantissa = bits & 0xfffffffffffffL; // Subnormal numbers; exponent is effectively one higher, // but there's no extra normalisation bit in the mantissa if (exponent==0) { exponent++; } // ... the bulk of the code handles converting the unnormalized mantissa/exponent to normalized form – Jimmy Dec 23 at 21:06...

We call -123456.7 the mantissa and 05 the exponent . The numeral by which the mantissa number begins ( 1 in the example above) is called the; 'most significant digit '. ... Exponent and Mantissa; We could also write -1234.567 = -123456.7 x 0.01; Since 0.01 = 10 to the -2th power, we can write -1234.567 as -123456.7 -02;

Perhaps the simplest solution to this problem is to introduce a (mantissa, exponent) representation similar to a floating point number. We do this using a mantissa which is a stream of either signed binary or dyadic digits, and and exponent is an integer of unrestricted size.

In order to define operations on the whole real line, a (mantissa,exponent) representation is used. The mantissa is either a dyadic or signed binary stream, and the exponent is an integer of unrestricted size.

forming a quantization value (L) from the coefficient K using a mantissa portion (Am(QP)) and an exponential portion (xAe(QP)). Typically, the value of x is 2. In some aspects of the method, forming a quantization value (L) from the coefficient K included L = K*A(QP) = K* Am(QP)*(2Ae(QP)).
