浮动t，检查;

.. ..

if（t check）

printf（"％f大于％f \ nt，检查）;

else

printf（％f小于％f \ nt，检查）;


不要比较平等，不会为漂浮（或双倍）工作，而是比较

差异agai NST适合您的准确性
一些delta b值$ B再见，乔乔

浮动t，检查;

...

if（t check）

printf（"％f大于％f\ n） t，check）;

else

printf（"％f小于％f \ nt，检查）;


不要比较平等，不适合浮动（或双倍），而是

比较适合您需要的某些delta的差异

准确度

oops，epsilon，而不是delta，在希腊字母中关闭一个......

实际上我想检查两个浮点值是否相等

等于

即假设t和t1是两个浮点数值我想检查一下是否

和t1是否相等


请以代码形式发送语法形式


请告诉我怎么做，

can anybody tell me how to compare two float values
say for example
t and check are two variables declared float how to compare t and
check
please help me as soon as possible

float t, check;
....
if ( t check)
printf("%f is greater than %f\n" t, check);
else
printf("%f is less than %f\n" t, check);

Don''t compare for equality, won''t work for float (or double), rather compare
the difference against some delta that suits your needs for accuracy

oops, epsilon, not delta, off by one in greek alphabeth...

actually i want to check wether two float values are equal or not
equal
i.e suppose t and t1 are two float values and i want to check wether t
and t1 are equal or not

please send in syntax form as in code form

please tell me how to do,
