Sets the number of cache strains to load once the final item allocation by utilizing the prefetch Guidance generated in compiled code. The default benefit is one if the final allotted object was an occasion, and three if it had been an array.

Handles huge log information. The selection might be in the shape of numberM or numberK. The default is set to 512K.

Returns the increased of two float values. That is certainly, the result is the argument closer to constructive infinity. In case the arguments contain the identical benefit, the result is that same price.

Returns the absolute value of a double worth. In the event the argument is just not negative, the argument is returned. If your argument is detrimental, the negation of the argument is returned. Specific cases:

Sets a tailor made command or possibly a number of semicolon-divided commands to operate when an irrecoverable mistake happens. In the event the string has Areas, then it needs to be enclosed in quotation marks.

Returns the double worth which is closest in benefit on the argument and is particularly equal to the mathematical integer. If two double values which can be mathematical integers are equally shut, The end result will be the integer price that's even. Special conditions:

You employ massive webpages, often known as massive web linked here pages, as memory internet pages that happen to be considerably bigger as opposed to regular memory page size (which differs dependant upon the processor and functioning process).
