standard/hypot(3) -- Euclidean distance, complex absolute value
|
|
hypot(x,y), fhypot(x,y), hypotf(x,y), hypotl(x,y), cabs(x,y), fcabs(x,y), cabsf(x,y), and cabsl(x,y) return sqrt(x*x+y*y) computed in such a way that overflow will not happen, and underflow occurs only if the final result deserves it. fhypot, hypotf, fcabs, and cabsf are the same functions as hypot and cabs but for the float data type. hypotl, and cabsl are the same functions as hypot and cabs but for the long double data type.... |

perl5/I18N::Collate(3) -- compare 8-bit scalar data according to the current locale *** WARNING: starting from the Perl version 5.003_06
|
|
This module provides you with objects that will collate according to your national character set, provided that the POSIX setlocale() function is supported on your system. You can compare $s1 and $s2 above with $s1 le $s2 to extract the data itself, you'll need a dereference: $$s1 This module uses POSIX::setlocale(). The basic collation conversion is done by strxfrm() which terminates at NUL characters being a decent C routine. collate_xfrm() handles embedded NUL characters gracefully. The avai... |

f90/iand(3) -- FORTRAN bitwise boolean functions
|
|
bool is the general name for the bit field manipulation intrinsic functions and subroutines from the FORTRAN Military Standard (MIL-STD1753). and, or and xor return the value of the binary operations on their arguments. not is a unary operator returning the one's complement of its argument. ior, iand, not, ieor - return the same results as and, or, not, and xor. lshift and rshift return the value of the first argument shifted left or right, respectively, the number of times specified by the sec... |

complib/icmax1(3) -- find the index of the element whose real part has maximum absolute value
|
|
ICMAX1 finds the index of the element whose real part has maximum absolute value. Based on ICAMAX from Level 1 BLAS. The change is to use the 'genuine' absolute value. Contributed by Nick Higham for use with CLACON. |

standard/iconsize(3) -- specifies the icon size of a window
|
|
x expects the width (in pixels) for the icon. y expects the height (in pixels) for the icon. |
|
standard/icontitle(3) -- assigns the icon title for the current graphics window.
|
|
name expects a pointer to the string containing the icon title. |

iconv(3c) -- code conversion function
|
|
The iconv() converts a string of characters from one codeset, in a input buffer, into a sequence of corresponding characters in another codeset in a output buffer. The cd is a conversion descriptor that was returned by the preceding iconv_open() function call which specifies the correct codeset converter. The inbuf points to a variable that points to the beginning of the input buffer that has the characters to be converted, and the variable pointed by in... |

iconv_close(3c) -- code conversion deallocation function
|
|
The iconv_close() function deallocates the conversion descriptor cd. It deallocates all other associated resources allocated by iconv_open() also. If a file descriptor is used to implement the type iconv_t, that file descriptor will be closed. The iconv_close() function may fail under the following conditions and set errno to the suitable value. [EBADF] The... |
|
iconv_open(3c) -- code conversion allocation function
|
|
The iconv_open() function returns a conversion descriptor that points to the suitable codeset converter. It describes a conversion from the codeset specified by the string pointed to by the fromcode argument to the codeset specified by the string pointed to by the tocode argument. A conversion descriptor can be used in a process until that process closes it. If a file descriptor is used to implement conversion descriptors, the FD_CLOEXEC flag... |
