In this article, we are going to learn about the use modf() function of math.h header file and use it with the help of an example.
C++ modf() function modf() functionis a library function ofcmathheader, it is used to get the fractional and integral parts of the given number. It accepts two arguments, the first argument is the value (float,double, orlong double), and the second argument is a pointer to store an in...
In a C program, modf always takes two double values and returns a double value.By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.RequirementsExpand table RoutineRequired header modf, modff, modfl C: <math.h> C++...
Learn how to use the modf function in Python to separate the fractional and integer parts of a floating-point number effectively.
Essentially, the std::modf function needs to have access to the cmath module in order to be executed by the compiler. Therefore,you must add the following #include header to the top of your code (in the include(s) part)such as: ...
Ifxis NaN, NaN is returned, and NaN is stored in*iptr. The returned value is exact,the current rounding modeis ignored Notes This function behaves as if implemented as follows: doublemodf(doublex,double*iptr){#pragma STDC FENV_ACCESS ONintsave_round=std::fegetround();std::fesetround(...

The modf function breaks down the floating-point value x into fractional and integer parts, each of which has the same sign as x. The signed fractional portion of x is returned. The integer portion is stored as a floating-point value at intptr. modf has an implementation that uses Streamin...
