Example:var_dump( (float) ‘NaN’ );PHP 5.x and HHVM:float(0)PHP 7.0:float(NAN) 10basetom ¶1 year ago I would use is_numeric() instead of ctype_digit() if you cannot be 100% sure what data type the string will be. Some examples of calculations that produce infinity or NaN: 1/0 = ∞ log (0) = -∞ sqrt (-1) = NaN When a calculation produces any of these values, an exception also occurs; see FP Exceptions. Inf and -Inf are positive and negative infinity whereas NaN means ‘Not a Number’. (These apply to numeric values and real and imaginary parts of complex values but not to values of integer vectors.) Inf and NaN are reserved words in the R language.


R: Finite, Infinite and NaN Numbers is.finite {base}R Documentation Description is.finite and is.infinite return a vector of the same length as x, indicating which elements are finite (not infinite and not missing) or infinite. Infinities propagate through calculations as one would expect: for example, 2 + ∞ = ∞, 4/∞ = 0, atan (∞) = π/2. NaN, on the other hand, infects any calculation that involves it. You can also deliberately set a floating-point variable to any of them, which is sometimes useful. Категория: Товары для детей Тип товаров: Детская молочная смесь Брэнд: Nestle. Value A logical vector of the same length as x: dim, dimnames and names attributes are preserved. This value is produced when you divide a positive number by negative infinity, or when a negative result is smaller than the limits of representation.

The GNU C Library: Infinity and NaN 20.5.2 Infinity and NaN IEEE 754 floating point numbers can represent positive or negative infinity, and NaN (not a number). These three values arise from calculations whose result is undefined or cannot be represented accurately. See Also NA, ‘Not Available’ which is not a number as well, however usually used for missing values and applies to many modes, not just numeric and complex. Предлагайте ребёнку смесь только в свежем виде. Не используйте остатки готового продукта от предыдущих кормлений.
