The quantexpd64function in C language Determines the exponent of a decimal floating-point number (_Decimal64). Note: This is part of the optional decimal floating-point arithmetic support.
The quantexpd64 function computes the quantum exponent of a _Decimal64 number. The quantum exponent is the power of 10 that the significand of the decimal floating-point number has to be scaled by to produce the given number. This function provides higher precision than quantexpd32 and is useful in financial calculations and other domains where exact decimal representation with higher precision is crucial.
The quantexpd64function takes 1 parameter:
  • •
    double `x`: The input value for which the quantized exponential will be computed.
Computes the exponential of the input `x` using a quantized representation for 64-bit floating-point values. Designed for applications requiring higher precision and efficient computation, such as numerical analysis or scientific computing. Returns the quantized exponential result as a `double`.
The quantexpd64 function return value :
  • Returns the quantum exponent of x

Output

This example demonstrates the use of quantexpd64 to determine the quantum exponents of two _Decimal64 numbers with different scales.
