bool islessequal( float x, float y ); |
(1) | (since C++11) (constexpr since C++23) |
bool islessequal( double x, double y ); |
(2) | (since C++11) (constexpr since C++23) |
bool islessequal( long double x, long double y ); |

bool islessequal( Arithmetic x, Arithmetic y ); |
(4) | (since C++11) (constexpr since C++23) |
1-3) Determines if the floating point number
x
is less than or equal to the floating-point number
y
, without setting floating-point exceptions.
4) A set of overloads or a function template for all combinations of arguments of arithmetic type not covered by
(1-3). If any argument has
integral type, it is cast to
double
.
Parameters
x | - | floating point value |
y | - | floating point value |
Return value
true
if x <= y
, false
otherwise.
Notes
The built-in operator<=
for floating-point numbers may raise FE_INVALID
if one or both of the arguments is NaN. This function is a "quiet" version of operator<=
.
