func almostEqual(x: T; y: T; unitsInLastPlace: int64): bool
Checks if two float values are almost equal, using the machine epsilon.
unitsInLastPlace is the max number of units in the last place difference tolerated when comparing two numbers. The larger the value, the more error is allowed. A 0 value means that two numbers must be exactly the same to be considered equal.
The machine epsilon has to be scaled to the magnitude of the values used and multiplied by the desired precision in ULPs unless the difference is subnormal.
func log(x: T; base: T): T
Computes the logarithm of x to base base.

func ^(x: T; y: 0..9223372036854775807): T
Computes x to the power of y.
The exponent y must be non-negative, use pow for negative exponents.

func splitDecimal(x: T): tuple[intpart: T, floatpart: T]
Breaks x into an integer and a fractional part.
Returns a tuple containing intpart and floatpart, representing the integer part and the fractional part, respectively.
Both parts have the same sign as x. Analogous to the modf function in C.
