              header

              <cmath> (math.h)

              C numerics library
              Header <cmath> declares a set of functions to compute common mathematical operations and transformations:

              Functions


              Trigonometric functions


              Hyperbolic functions


              Exponential and logarithmic functions


              Power functions


              Error and gamma functions


              Rounding and remainder functions


              Floating-point manipulation functions


              Minimum, maximum, difference functions


              Other functions


              Macros / Functions

              These are implemented as macros in C and as functions in C++:

              Classification macro / functions


              Comparison macro / functions


              Macro constants


              This header also defines the following macro constants (since C99/C++11):
              macrotypedescription
              MATH_ERRNO
              MATH_ERREXCEPT
              intBitmask value with the possible values math_errhandling can take.
              FP_FAST_FMA
              FP_FAST_FMAF
              FP_FAST_FMAL
              intEach, if defined, identifies for which type fma is at least as efficient as x*y+z.
              FP_INFINITE
              FP_NAN
              FP_NORMAL
              FP_SUBNORMAL
              FP_ZERO
              intThe possible values returned by fpclassify.
              FP_ILOGB0
              FP_ILOGBNAN
              intSpecial values the ilogb function may return.
