Printing Numbers

Print values directly or embed them using string interpolation with \(value).

Example

let a = 7, b = 3
print(a, b)                 // space-separated by default
print("a=\(a), b=\(b)")     // interpolation
print("sum = \(a + b)")     // inline math

This example prints numbers directly and via string interpolation, including inline addition.

Math Functions

Common functions like abs, min, and max help compute numeric results.

• abs(x) returns the absolute value of x.
• min(x, y) returns the smaller of x and y.
• max(x, y) returns the larger of x and y.

Example

let x = -7
print(abs(x))          // 7
print(min(3, 8))       // 3
print(max(3, 8))       // 8

This example shows absolute value, minimum, and maximum functions.
