C++ Math rint() Function
C++ Math rint() Function with tutorial for beginners and professionals with examples on isgreaterequal(), less(), islessequal(), islessgreater(), isunordered(), exp(), frexp(), ldexp(), log(), log10(), modf(), exp2(), expm1(), log1p(), log2(), logb(), scalbn(), scalbln() etc.
C++ Math rint()The function rounds off the given value to the nearest integer using current rounding mode. The current rounding mode is determined by fesetround(). For example: rint(7.9) = 8; if, fesetround(FE_DOWNWARD) then, rint(7.9) = 7; Syntax
Suppose a number 'x'. Syntax would be: return_type rint(data_type x); Note: The return_type can be float, double or long double.Parameter
x: The value that can be either float or double. Return valueIt returns the rounded value of x. Example 1
Let's see a simple example. #include Output: Value of x is :9.9 Rounding to nearest,value is :10 Rounding to upward,value is :10 Rounding to downward,value is :9
