math.abs

from "math" import abs

Returns the absolute value of x

Parameters

Return value

x with its sign removed. The result keeps the type of x: an integer argument gives an integer back, a float argument gives a float back. Use fabs when a float result is wanted regardless of the argument's type.

Notes

The smallest representable integer has no positive counterpart at the same width, so taking its absolute value overflows and returns that same negative value unchanged.

Example

from "math" import abs

println("abs(-3) =", abs(-3))
println("type(abs(-3)) =", type(abs(-3)))

// the result keeps the argument's type: a float argument gives a float back
println("abs(-3.0) =", abs(-3.0))
println("type(abs(-3.0)) =", type(abs(-3.0)))

abs(-3) = 3
type(abs(-3)) = integer
abs(-3.0) = 3
type(abs(-3.0)) = float
