## Documentation

Limits for machine number types.

Note that while this egg is named *number-limits* the actual extension is *int-limits* and *float-limits*.

### Integer Limits

- machine-word-bits
- Number of bits in machine word - C_word
- maximum-machine-word
- Largest machine word value - C_uword
- most-negative-machine-word
- Smallest negative machine word value - C_word
- most-positive-machine-word
- Largest positive machine word value - C_word
- unsigned-integer32-size
- Sizeof uint32_t
- maximum-unsigned-integer32
- Largest value for uint32_t
- char-size
- Sizeof the C type
- unsigned-char-size
- Sizeof the C type
- short-size
- Sizeof the C type
- unsigned-short-size
- Sizeof the C type
- int-size
- Sizeof the C type
- unsigned-int-size
- Sizeof the C type
- long-size
- Sizeof the C type
- unsigned-long-size
- Sizeof the C type
- long-long-size
- Sizeof the C type, -1 when unsupported
- unsigned-long-long-size
- Sizeof the C type, -1 when unsupported

### Float Limits

- float-radix
- Representation base of floating point number
- maximum-float
- Largest floating point number
- minimum-float
- Smallest floating point number
- float-epsilon
- The difference between 1.0 and the least value > 1.0 of a floating point number
- float-precision
- Number of digits in mantissa base radix of floating point number
- float-decimal-precision
- Number of digits in mantissa base 10 of floating point number
- float-maximum-exponent
- Largest exponent in base radix of floating point number
- float-minimum-exponent
- Smallest exponent in base radix of floating point number
- float-maximum-decimal-exponent
- Largest exponent in base 10 of floating point number
- float-minimum-decimal-exponent
- Smallest exponent in base 10 of floating point number
- maximum-double
- Largest floating point number
- minimum-double
- Smallest floating point number
- double-epsilon
- The difference between 1.0 and the least value > 1.0 of a floating point number
- double-precision
- Number of digits in mantissa base radix of floating point number
- double-decimal-precision
- Number of digits in mantissa base 10 of floating point number
- double-maximum-exponent
- Largest exponent in base radix of floating point number
- double-minimum-exponent
- Smallest exponent in base radix of floating point number
- double-maximum-decimal-exponent
- Largest exponent in base 10 of floating point number
- double-minimum-decimal-exponent
- Smallest exponent in base 10 of floating point number

No `long-double` information since `long double` is not a supported return type.
