Is it minus 1 or negative 1?
In mathematics, −1 (also known as negative one) is the additive inverse of 1, that is, the number that when added to 1 gives the additive identity element, 0. It is the negative integer greater than negative two (−2) and less than 0. Negative one has some similar but slightly different properties to positive one.
What is the power of negative 1?
The negative power will become just “1” once I move the base to the other side of the fraction line. Anything to the power 1 is just itself, so I’ll be able to drop this power once I’ve moved the base.
How do you round a negative number?
Rounding to the next integer in the negative direction. The modern nomenclature is the floor function, symbolized as ⌊x⌋. −7.4, −7.5, −7.6 all go to −8; 7.4, 7.5, 7.6 all go to 7; −8.5 goes to −9; 8.5 goes to 8. Thus, ⌊−x⌋ = −⌊x⌋ if and only if x is an integer.
Is negative 0.5 rounded up or down?

Which is nearest negative integer to zero?
For negative numbers, it’s opposite of positive numbers. Rule # 3 says with negative numbers, the integer closest to zero is of greater value. For the two negative integers, if I draw a line from zero to each of them, -1.2 is closest to zero. Using this rule, -1.2 is the larger of the two negative numbers.”
Do you round down to zero?
ROUNDDOWN behaves like ROUND, except that it always rounds a number down. If num_digits is 0, then number is rounded down to the nearest integer. If num_digits is less than 0, then number is rounded down to the left of the decimal point.
