Bytes parse human

bytes-parse-human · version 1.0.0 · Other utilities · free, no key needed

Parse an SI or IEC byte-size string and return an exact integer byte count using explicit rounding.

Use when you need to: parse a human file size · turn 1.5 GiB into bytes · convert 300 MB to exact bytes.

Decide before calling

Read the versioned contract and the supported scope below. Reuse bytes-parse-human@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use bytes-parse-human@1.0.0 for parse a human file size. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• parse a human file size
• turn 1.5 GiB into bytes
• convert 300 MB to exact bytes
• parse 10 kB
• human size to byte count
• read SI or IEC storage size

Not supported

• format a byte count
• parse bit-rate units

Behavior

• Accepted grammar is a canonical non-negative decimal, optional single ASCII space, then B, kB, MB, GB, TB, PB, KiB, MiB, GiB, TiB or PiB.
• SI units use powers of 1000 and IEC units use powers of 1024.
• Fractional bytes use half_even, half_up, or down exactly; no binary floating-point arithmetic is used.

Input

• text (string, required): min length 1; max length 128
• rounding (one of "half_even", "half_up", "down", required)

Output

• bytes (string, required): pattern ^(0|[1-9][0-9]*)$
• rounding (one of "half_even", "half_up", "down", required)
• standard_version (constant "IEC 80000-13:2008; SI Brochure, 9th edition (2019, updated 2022)", required)

Limits

• max input bytes: 128
• max digits: 30
• max output bytes: 512
• max iterations: 0

Example

Request input:

{
  "text": "1.5GiB",
  "rounding": "half_even"
}

Response:

{
  "result": {
    "bytes": "1610612736",
    "rounding": "half_even",
    "standard_version": "IEC 80000-13:2008; SI Brochure, 9th edition (2019, updated 2022)"
  }
}
