The result contains a decimal point if required, and trailing zeros after the decimal point are omitted.
WebJun 6, 2024 · If you're writing C, just use an appropriate fixed width integer type like uint_fast32_t (the fastest unsigned int with at least 32 bits), instead of less clear types like long.

WebIt can optionally contain embedded format specifiers that are replaced by the values specified in subsequent additional arguments and formatted as requested. A format specifier follows this prototype: [ see compatibility note below] % [flags] [width] [.precision] [length]specifier Web#Data Types # Fixed Width Integer Types (since C99) The header provides several fixed-width integer type definitions. These types are optional and only provided if the platform has an integer type of the corresponding width, and if the corresponding signed type has a two's complement representation of negative values.. See the remarks section …
WebThe correct conversion specifications for the fixed-width integer types (int8_t, etc) are defined in the header (although SCNdMAX, SCNuMAX, etc is synonymous with % jd, % ju, etc). There is a sequence point after the action of each conversion specifier; this permits storing multiple fields in the same "sink" variable.
