Scalar isa single number or value. ... In Perl 5 and above and most programming languages a scalar is a single value that is not an array. A scalar may be string, integer, or a floating-point. For example, "my $value="example";" is an example of a scalar in Perl, where $value...
Meanwhile, most young people in the West are expected to leave what could be life's most momentous decision—marriage—almost entirely up to luck. 同时,人们认为西方的大多数年轻人把婚姻这一可能是人生最重要的决定几乎完全交由命运来安排。 柯林斯高阶英语词典 He drinks what is left in his glass ...
Whether it’s right or wrong, a “backpropagation” algorithm adjusts the parameters—that is, the formulas’ coefficients—in each cell of the stack that made that prediction. The goal of the adjustments is to make the correct prediction more probable. “It does this for right answers, too...
Machine learning and AI are often discussed together, and the terms are sometimes used interchangeably, but they don’t mean the same thing. In short, all machine learning is AI, but not all AI is machine learning. Key Takeaways Machine learning is a subset of AI. The four most common ...
The first is wrong because the array index can be negative if the hash code is negative; the second does not classify -123 as an odd number.The % operator does not give the canonical modulus, it gives the remainder. Anonymous December 04, 2011 ...

One application of exact rounding occurs in multiple precision arithmetic. There are two basic approaches to higher precision. One approach represents floating-point numbers using a very large significand, which is stored in an array of words, and codes the routines for manipulating these numbers in...
thx for your advice.@Simon: it's not about the hashcode, the array creation is too expensive. int/long/struct make the fastest dict keys, then string, int tuple, then int array. So we work with long, or string if the key doesn't fit in 64b. ...
