min

This function has four variants:

* Int min(Int, Int)
* Float min(Int, Float)
* Float min(Float, Int)
* Float min(Float, Float)

Returns the smaller of two values. If both values are Ints, the return value is an Int, otherwise it is a Float.

Parameters:

1. Int|Float: the first number to compare.
2. Int|Float: the second number to compare.

Returns: The smaller of the two arguments.

Example: test_min.wdl

version 1.2

workflow test_min {
  input {
    Int value1
    Float value2
  }

  output {
    # these two expressions are equivalent
    Float min1 = if value1 < value2 then value1 else value2
    Float min2 = min(value1, value2)
  }
}

{
  "test_min.value1": 1,
  "test_min.value2": 2.0
}

{
  "test_min.min1": 1.0,
  "test_min.min2": 1.0
}
