Short
Name Function
from
ulong void s32_from_ulong(unsigned long arg1, s32_type *arg2);
Converts a Neuron C unsigned long integer (range 0 to +65,535) to a
signed 32-bit integer.
Conversion of Signed 32-bit to ASCII String
Table 18 lists the conversion function for a signed 32-bit number to an ASCII
string.

Short
Name Function
to
ascii void s32_to_ascii(const s32_type *arg1, char *arg2);
Converts a signed 32-bit integer *arg1 to an ASCII string followed by a
terminating null character. The *arg2 output buffer should be at least
12 bytes long. The general output format is [-]xxxxxxxxxx, with one to
ten digits.
Conversion of ASCII String to Signed 32-bit
Table 19 lists the conversion function for an ASCII string to a signed 32-bit
number.
Table 19. Conversions of ASCII Strings to Signed 32-Bit Numbers
Short
Name Function
from
ascii void s32_from_ascii(const char *arg1, s32_type *arg2);
Converts an ASCII string arg1 to a signed 32-bit integer in *arg2. The
conversion stops at the first invalid character in the input buffer – there
is no error notification. The acceptable format is [-]xxxxxxxxxx. The
number of digits should not exceed ten. Embedded spaces within the
string are not allowed.
Signed 32-Bit Performance
Table 20 on page 58 lists times in milliseconds for the various 32-bit functions.
They were measured using a Series 3100 Neuron Chip with a 10 MHz input
clock. These values scale with a faster or slower clock. The measurements are
maximums and averages over random data uniformly distributed in the range [-
2,147,483,648 to +2,147,483,647].
