IEEE floating-point functions
The following sections describe the IEEE floating-point functions.
- __chkbfp() — check IEEE facilities usage
- __fp_btoh() — convert from IEEE floating-point to hexadecimal floating-point
- __fp_cast() — cast between floating-point data types
- __fp_htob() — convert from hexadecimal floating-point to IEEE floating-point
- __fp_level() — determine type of IEEE facilities available
- __fp_read_rnd() — determine rounding mode
- __fp_setmode() — set IEEE or hexadecimal mode
- __fp_swapmode() — set IEEE or hexadecimal mode
- __fp_swap_rnd() — swap rounding mode
- __fpc_rd() — read floating-point control register
- __fpc_rs() — read floating-point control register and change rounding mode field
- __fpc_rw() — read and write the floating-point control register
- __fpc_sm() — set floating-point control register rounding mode field
- __fpc_wr() — write the floating-point control register
- __isBFP() — determine application floating-point mode
- __to_xx() – C/C++ compiler casting support
