- (Subtraction Operator)
Description: Subtracts the second number from the first. Integer operands give an int; if the result overflows, the Arith handler installed around the code chooses the value. Constant expressions such as the one below are evaluated at compile time. See Arithmetic Effects.
With a float operand, the result is a float. Floating-point arithmetic follows IEEE-754: infinity and NaN remain values, and underflow preserves subnormal values and signed zero. It does not request an integer overflow policy. See the float result contract.
Example
let result = 10 - 4 // result = 6result = 10 - 4 // result = 6
