LibrariesPower and absolute-value functionscabscabsfcabslReturns the complex absolute value of z (also known as norm,modulus or magnitude).cpowcpowfcpowlReturns the complex value of x raised to the power y (x y ) whereboth x and y are complex numbers.csqrtcsqrtfcsqrtlReturns the complex square root of z.Manipulation functionscargcargfcarglReturns the argument of z (also known as phase angle).cimagcimagfcimaglReturns the imaginary part of z as a real (respectively as a double,float, long double)conjconjfconjlReturns the complex conjugate value (the sign of its imaginary partis reversed).cprojcprojfcprojlReturns the value of the projection of z onto the Riemann sphere.crealcrealfcreallReturns the real part of z as a real (respectively as a double,float, long double)13.2.3. cstart.hThe header file cstart.h controls the system startup code's general settings and register initializations.It contains defines only, no functions.13.2.4. ctype.h and wctype.hThe header file ctype.h declares the following functions which take a character c as an integer typeargument. The header file wctype.h declares parallel wide-character functions which take a characterc of the wchar_t type as argument.ctype.hisalnumisalphaisblankiscntrlisdigitisgraphislowerisprintispunctwctype.hiswalnumiswalphaiswblankiswcntrliswdititiswgraphiswloweriswprintiswpunctDescriptionReturns a non-zero value when c is an alphabetic character or anumber ([A-Z][a-z][0-9]).Returns a non-zero value when c is an alphabetic character([A-Z][a-z]).Returns a non-zero value when c is a blank character (tab, space...)Returns a non-zero value when c is a control character.Returns a non-zero value when c is a numeric character ([0-9]).Returns a non-zero value when c is printable, but not a space.Returns a non-zero value when c is a lowercase character ([a-z]).Returns a non-zero value when c is printable, including spaces.Returns a non-zero value when c is a punctuation character (suchas '.', ',', '!').743
