The sign s of the float. tt if negative.
The exponent e of the float in the base given by radix. emin ≤ e ≤ emax. Returns none if the number is not finite.
Decompose the number f in to (s,e) where 0.5 ≤ s < 1.0 and emin ≤ e ≤ emax such that f = s * 2 ^ e.
Decompose in to integer fst and fractional snd parts.
mantissa f returns a number s where 0.5 ≤ s < 1.0 such that there exists an integer e such that f = s * 2 ^ e
remainder of the floating point division operation.
signed remainder of the division operation.
atan2 y x finds the angle anticlockwise from the x-axis to the point [x,y].
Nearest integer not less than the given value.
Nearest integer not greater than the given value.
Nearest integer not greater in magnitude than the given value.
Round to the nearest integer, rounding away from zero in halfway cases.
