6.6.12.5 Interpreting Bytevector Contents as Floating Point Numbers ¶
Bytevector contents can also be accessed as IEEE-754 single- or
double-precision floating point numbers (respectively 32 and 64-bit
long) using the procedures described here.
- Scheme Procedure: bytevector-ieee-single-ref bv index endianness ¶
- Scheme Procedure: bytevector-ieee-double-ref bv index endianness ¶
- C Function: scm_bytevector_ieee_single_ref (bv, index, endianness) ¶
- C Function: scm_bytevector_ieee_double_ref (bv, index, endianness) ¶
Return the IEEE-754 single-precision floating point number from bv
at index according to endianness.
- Scheme Procedure: bytevector-ieee-single-set! bv index value endianness ¶
- Scheme Procedure: bytevector-ieee-double-set! bv index value endianness ¶
- C Function: scm_bytevector_ieee_single_set_x (bv, index, value, endianness) ¶
- C Function: scm_bytevector_ieee_double_set_x (bv, index, value, endianness) ¶
Store real number value in bv at index according to
endianness.
Specialized procedures are also available:
- Scheme Procedure: bytevector-ieee-single-native-ref bv index ¶
- Scheme Procedure: bytevector-ieee-double-native-ref bv index ¶
- C Function: scm_bytevector_ieee_single_native_ref (bv, index) ¶
- C Function: scm_bytevector_ieee_double_native_ref (bv, index) ¶
Return the IEEE-754 single-precision floating point number from bv
at index according to the host’s native endianness.
- Scheme Procedure: bytevector-ieee-single-native-set! bv index value ¶
- Scheme Procedure: bytevector-ieee-double-native-set! bv index value ¶
- C Function: scm_bytevector_ieee_single_native_set_x (bv, index, value) ¶
- C Function: scm_bytevector_ieee_double_native_set_x (bv, index, value) ¶
Store real number value in bv at index according to
the host’s native endianness.
