## Function Documentation

## ◆ type_util_double_to_uint64()

WS_DLL_PUBLIC uint64_t type_util_double_to_uint64 | ( | double | value | ) |

Converts a double-precision floating-point value to a 64-bit unsigned integer.

Safely casts a double to a uint64_t, truncating any fractional part.

Parameters

  value | The double value to convert.

Returns
  The corresponding uint64_t value.

## ◆ type_util_uint64_to_double()

WS_DLL_PUBLIC double type_util_uint64_to_double | ( | uint64_t | value | ) |

Converts a 64-bit unsigned integer to a double-precision floating-point value.

Casts a uint64_t to a double, preserving the full integer value.

Parameters

  value | The uint64_t value to convert.

Returns
  The corresponding double value.
