Hi everyone! Anbody an idea how I could do this more nicely?

def avail_mem = task.memory == null ? '' : "-m ${Math.floor(task.memory.toBytes() / task.cpus)}"

I want to define in samtools sort the parameter -m <X> for memory per thread. thats why I take the task.memory, transform to bytes and divide by CPUs. I got that specific error:

samtools sort \
      CMT_Project04172015_20150063001_S_6_bwa.sam \
      -@ 10 -m 4.29496729E8 \
      -o CMT_Project04172015_20150063001_S_6_bwa.sam.sorted.bam

Command exit status:

Command output:

Command error:
  [bam_sort] -m setting (4 bytes) is less than the minimum required (1M).
Thought that Math.floor(double d) does the job to transform this to an integer (because I had something like 424322000.6 bytes or similar at some point, which was weird...)

avail_mem = task.memory ? "-m ${task.memory.toBytes().intdiv(task.cpus)}" : ''
