DESCRIPTION <\/a> <\/h2>\nThese functions compute x<\/i> bodies manpages.csv script_extrae_body.sh script.sh usr y<\/i> + z<\/i>. The result is rounded as one ternary operation according to the current rounding mode (see fenv<\/b>(3)).<\/p>\nRETURN VALUE <\/a> <\/h2>\nThese functions return the value of x<\/i> bodies manpages.csv script_extrae_body.sh script.sh usr y<\/i> + z<\/i>, rounded as one ternary operation.<\/p>\n
If x<\/i> or y<\/i> is a NaN, a NaN is returned.<\/p>\n
If x<\/i> times y<\/i> is an exact infinity, and z<\/i> is an infinity with the opposite sign, a domain error occurs, and a NaN is returned.<\/p>\n
If one of x<\/i> or y<\/i> is an infinity, the other is 0, and z<\/i> is not a NaN, a domain error occurs, and a NaN is returned.<\/p>\n
If one of x<\/i> or y<\/i> is an infinity, and the other is 0, and z<\/i> is a NaN, a domain error occurs, and a NaN is returned.<\/p>\n
If x<\/i> times y<\/i> is not an infinity times zero (or vice versa), and z<\/i> is a NaN, a NaN is returned.<\/p>\n
If the result overflows, a range error occurs, and an infinity with the correct sign is returned.<\/p>\n
If the result underflows, a range error occurs, and a signed 0 is returned.<\/p>\n
ERRORS <\/a> <\/h2>\nSee math_error<\/b>(7) for information on how to determine whether an error has occurred when calling these functions.<\/p>\n
The following errors can occur:
Domain error: x<\/i> bodies manpages.csv script_extrae_body.sh script.sh usr y<\/i> + z<\/i>, or x<\/i> bodies manpages.csv script_extrae_body.sh script.sh usr y<\/i> is invalid and z<\/i> is not a NaN<\/p>\n
An invalid floating-point exception (FE_INVALID<\/b>) is raised.<\/p>\n
Range error: result overflow<\/p>\n
An overflow floating-point exception (FE_OVERFLOW<\/b>) is raised.<\/p>\n
Range error: result underflow<\/p>\n
An underflow floating-point exception (FE_UNDERFLOW<\/b>) is raised.<\/p>\n
These functions do not set errno<\/i>.<\/p>\nVERSIONS <\/a> <\/h2>\nThese functions first appeared in glibc in version 2.1.<\/p>\n
