Fixed point vs Floating point number
...of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.
Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the...
Any way to modify Jasmine spies based on arguments?
...pi, 'get')
.withArgs('abc').and.returnValue('Jane')

df_melt <- melt(df1, id = c("date", "year", "month"))
dcast(df_melt, year + month ~ variable, sum)
# year month x1 ...

Convert NaN to 0 in javascript
...ber. This has the added benefit of converting things like numeric strings '123' to a number.
The only unexpected thing may be if someone passes an Array that can successfully be converted to a number:

Why should I use Hamcrest-Matcher and assertThat() instead of traditional assertXXX()-Methods
...w advantages over hamcrest such as:
they are more readable
(assertEquals(123, actual); // reads "assert equals 123 is actual" vs
assertThat(actual).isEqualTo(123); // reads "assert that actual is equal to 123")
they are discoverable (you can make autocompletion work with any IDE).
