Functions ¶
func Acos ¶
Asin returns the arcsine, in radians, of x.
Special cases are:
Asin(±0) = ±0 Asin(x) = NaN if x < -1 or x > 1
func Asin ¶
Asin returns the arcsine, in radians, of x.
Special cases are:
Asin(±0) = ±0 Asin(x) = NaN if x < -1 or x > 1
func Ceil ¶
Ceil returns the least integer value greater than or equal to x.
Special cases are:
Ceil(±0) = ±0 Ceil(±Inf) = ±Inf Ceil(NaN) = NaN
func Cos ¶
Cos returns the cosine of the radian argument x.
Special cases are:
Cos(±Inf) = NaN Cos(NaN) = NaN
func Floor ¶
Floor returns the greatest integer value less than or equal to x.
Special cases are:
Floor(±0) = ±0 Floor(±Inf) = ±Inf Floor(NaN) = NaN
func Mod ¶
Mod returns the floating-point remainder of x/y. The magnitude of the result is less than y and its sign agrees with that of x.
Special cases are:
Mod(±Inf, y) = NaN Mod(NaN, y) = NaN Mod(x, 0) = NaN Mod(x, ±Inf) = x Mod(x, NaN) = NaN
func Pow ¶
Pow returns x**y, the base-x exponential of y.
Special cases are (in order):
Pow(x, ±0) = 1 for any x Pow(1, y) = 1 for any y Pow(x, 1) = x for any x Pow(NaN, y) = NaN Pow(x, NaN) = NaN Pow(±0, y) = ±Inf for y an odd integer < 0 Pow(±0, -Inf) = +Inf Pow(±0, +Inf) = +0 Pow(±0, y) = +Inf for finite y < 0 and not an odd integer Pow(±0, y) = ±0 for y an odd integer > 0 Pow(±0, y) = +0 for finite y > 0 and not an odd integer Pow(-1, ±Inf) = 1 Pow(x, +Inf) = +Inf for |x| > 1 Pow(x, -Inf) = +0 for |x| > 1 Pow(x, +Inf) = +0 for |x| < 1 Pow(x, -Inf) = +Inf for |x| < 1 Pow(+Inf, y) = +Inf for y > 0 Pow(+Inf, y) = +0 for y < 0 Pow(-Inf, y) = Pow(-0, -y) Pow(x, y) = NaN for finite x < 0 and finite non-integer y
func Round ¶
Round returns the nearest integer, rounding half away from zero.
Special cases are:
Round(±0) = ±0 Round(±Inf) = ±Inf Round(NaN) = NaN
